Series One: The 39 Clues
The novels revolve around Amy and Dan Cahill, two orphans who, upon their grandmother's death, discover that they are members of the Cahill family, whose members have shaped the history of their world. The ancestors of the Cahill family are Gideon and Olivia Cahill, whose children created the branches of the family. The branches constantly compete against each other in a hunt for the 39 Clues, ingredients to a serum, the source of the family's power. Amy and Dan, along with their au pair Nellie, enter the hunt for the Clues and become embroiled in the conflict between the Cahill branches. As Amy and Dan participate in the hunt, they unearth secrets about their Cahill ancestors, their parents, and the Madrigals, a mysterious organization.
Each book chronicles one location to which Amy, Dan, and Nellie travel and focuses on one historical character with whom a Clue has a link. The main narrative focuses on Amy and Dan's pursuit of the Clues while evading the sabotage of their competitors, Cahills from other branches. The books also contain the perspectives of the other Cahills as their view of Amy and Dan changes. The environment all of the authors have created is an alternative reality in which influential historical figures all belong to a single family. The world of The 39 Clues exists in parallel with the real world; other than the Cahills, no one knows that the Cahills exist or how much they have shaped the world.
Book 1: The Maze of Bones
Released September 9, 2008, The Maze of Bones is the first book in the series, written by Rick Riordan.

Amy and Dan enter the Clue hunt, competing against more experienced Clue hunters: the athletic Holts, brilliant Alistair Oh, the genius Starlings, the cunning and deadly Kabras, famous Jonah Wizard, and hardcore Irina Spasky. Pursuing clues hidden in Grace's library and in the Franklin Institute, Dan and Amy discover that Benjamin Franklin has hidden a clue in Paris. After convincing their au pair, Nellie, to chaperone their trip, Amy and Dan travel to Paris. While on the journey, Amy and Dan discover the conflict-ridden history of the Cahills that Grace hid from them to protect them. Racing through Paris—above ground and underground—the siblings solve codes and ciphers and find the clue in a vial.

|Preceded by||The Medusa Plot|
|Followed by||The Dead of Night|
A King's Ransom, written by Jude Watson, was released December 6, 2011. Amy and Dan are wandering in Santa Maria Novella train station in Florence when they come across a girl named Vanessa Mallory, who is Cheyenne Wyoming in disguise, and use her as a distraction to get into the train for Lucerne, Switzerland where Vesper One is sending them for their next mission: find the De Virga world map. Once on the train, the siblings realize that they have been tricked, and an Interpol agent named Milos Vanek tries to hunt them down. They escape the train by hiding inside luggage bags and disembark at Enderberg.
They disguise themselves as rich heirs to enter an auction house in Lucerne. They sneak into the office and retrieve the de Virga Map archives written in German. Ian translates it, revealing that four people, Otto Hummer the professor, Jane Sperling the socialite, Marcel Maubert the art dealer, and Reginald Tawnley the person who owned a private library, have something to do with the map. Unfortunately, the report about Amy and Dan's criminal heists have reached the auction house, but they escape by creating diversions.
Later, William McIntyre meets Amy and Dan inside a Blue Sedan, gives them a GPS wrist watch, and drops them off at a safe house in Basel. Sinead and Evan share the information about the four listed in the archives: Maubert and Tawnley died in war, Hummel worked in the Nazi party, and Jane was a Jew whom the Cahills believe tried to protect the de Virga map, which was owned by a Jewish family.
Dan gathers ingredients to create the Master Serum, which he intends to use as backup. Using the information the center gathered, Amy concludes that they have to search Neuschwanstein Castle.
After calling for backup, Jonah and Hamilton both come to Munich on their way to the castle but accidentally pick up Cheyenne Wyoming, who nearly kills them. Amy and Dan find a black notebook owned by Sparrow, a.k.a. Jane Sperling at the castle. Inside is a note that leads to the de Virga map. By another stroke of bad luck, Casper bumps into them and almost kills them, but Jonah and Hamilton rescue them.
Analysis comes from the Command Center about the notes: they are about a Johannes Kepler book that was recovered from the castle to the Library of Philosophy and Cosmology in Prague, Czech Republic. They head there to investigate the book but cannot do so without a reference. They try to use Rosenbloom's father but fail. At the hotel, they again escape from Milos Vanek.
After going to Sedlec Ossuary on a hunch from the Command Center, they discover a flash drive file about a Vesper One report and the initials AJT, Arthur Josiah Trent, carved on the wall, which shocks Dan because Arthur was their father. They then call Erasmus, who answers all their questions about Arthur. He explains how Arthur was initiated into the Vespers but later cut off all ties with them. Afterwards, Ian calls to tell Amy that a Lucian professor has agreed to help Dan and Amy enter the Library of Philosophy.
After going to the library, they bump into Jake and Atticus outside. Although Jake is originally inclined to call the Interpol, Atticus urges him to wait upon seeing the picture of Jane Sperling, who is his great grandmother. Atticus and Jake both decide to help the siblings. Inside, Katja Mavel, the director of the library, gives them what they want. Jake succeed in luring her away, and that leaves Dan, Amy, and Atticus. They finally find the map inside the book itself.
In Rome, a Vesper dressed like a waiter kills William, who leaves a secret message in his shoe before he dies.
Back in Prague, Amy and Dan tell Atticus what they are doing, and Atticus reveals his involvement as a Guardian. The siblings have never heard of the group. Dan connects Il Milione and the map to Samarkand, Uzbekistan - their next destination. Vesper One asks them to drop off the package at the Astronomical Tower, near the statue of Jan Hus. They do what is asked, but it goes wrong. Atticus follows them and is kidnapped.
Vesper One now knows Dan and Amy have been hiding Marco Polo's epilogue all this time and explains that Atticus was the price of keeping it from him. Minutes later, another message is sent to Dan's phone, apparently from AJT.

During a capoeira performance, a capoeirista "accidentally" injures Atticus. At the Falls, a second attack occurs, and a blow dart coated with curare meant to hit Atticus hits Dan instead. A doctor nearby saves Dan from the poison. They realize Isabel Kabra orchestrated the attacks, and that there will be one more, when Amy remembers that the capoeirista told her: Um, dois, tres (One, two, three in Portuguese), and Amor to the littlest, from Isabel.

LaCher took the knife to her neck and was taken to a hospital. She tells Dan "You know... You know," before fainting. They find the folio and realize that Archimedes plays a part in the Vespers' master plan. They suspect Isabel to be Vesper One and ask Hamilton and Jonah to find out more about Archimedes at Syracuse. Before Dan and Amy go to the drop off, a video on the DeOssie phone shows a gun at Nellie's temple and the trigger twitching, before being abruptly cut off.

Traumatized, Amy hides in her own mind, blocking out the real world. Dan decides that the team should go to Attleboro and Evan, having been contacted by Dan, says he wanted to talk to Amy, but Dan tells him that she is in no condition to do so.

Series Four: Doublecross
On April 26, 2014, at the New Hampshire Worlds Collide event, it was announced that the 39 Clues would get a fourth and final series titled, Doublecross.
Scholastic has expanded the 39 Clues universe with several books. In 2010 Scholastic published Agent Handbook, which explores the techniques that the clue hunters in the series use to find clues, and The Black Book of Buried Secrets, which provides more information about events in the series. In the last week of December 2011, the Scholastic editorial team released seven short stories as part of The 39 Clues: Rapid Fire e-book series.[dead link] The editorial team has also released "The Cahill Files", which includes Operation Trinity, Spymasters, and four e-books. As part of the multimedia interactive experience to promote the series, Scholastic includes six cards in each book of the 39 Clues series. Each card leads to one online clue, which readers can unlock by entering the code on the cards on their 39 Clues account online.
The 39 clues also uses collectible cards in order to expand readers' experience of the series. In the first series of books, The Clue Hunt, each book came with six game cards. These cards all shared the same code and once added online would unlock the clue in that book. Alongside the first series of books, Card Packs were sold. These card packs contained 16 random cards out of a total of roughly 50 that were not available in the books. The card packs were: Card Pack - for books 1, 2 and 3 Card Pack 2: Branch vs. Branch - for books 4, 5 and 6 Card Pack 3: Rise of the Madrigals - for books 7 and 8 Ultimate Card Pack - for books 9 and 10
In the second series each book again came with six cards. However, unlike the first series, the cards were needed to unlock the online missions. Cahills vs Vespers also had two card packs. These card packs all contained the same 16 game cards, which would unlock the online extreme missions. The card packs were: The Marco Polo Heist - released with book 1 The Magellan Heist - released with book 4
In the third series Unstoppable, each book contains six game cards. These cards unlock an extra game in their corresponding online missions.
Overall, the cards are a key part of the series. Players on the online website can only collect all the clues through the use of the cards, and in later series can only unlock the missions by having the cards. The cards in the first series often had puzzles and riddles to find out.
Additional cards have been released over the course of the series, and the cards are only virtual. A game involving the cards, Doublecross, was created by Scholastic in which players physically use their cards to battle their opponents.
The 39 Clues series consists of adventure novels; however, the novels also fall within the genre of historical fiction. The stories switch back and forth between different characters' points of view. Each novel focuses on one historical figure and geographical location as Dan and Amy explore a clue related to a prominent Cahill family member in an exotic location.
One theme of the series is the relationship between talent and success. Each branch of the Cahill family has specific talents in a certain area; for example, the Ekaterina branch specializes in inventions and technology. Amy and Dan's competitors' talents give them an advantage, yet Amy and Dan consistently are ahead in the hunt and are viewed as the main threats. Over the course of the books, Amy and Dan discover their own talents.
An editorial team in Scholastic came up with idea of an interactive series with online games and asked Rick Riordan to write the first book. Riordan agreed because he thought it was a good idea, and as a middle school teacher, he loved making history enjoyable for younger readers. The project was kept secret for about two years.
As of June 11, 2010, The 39 Clues series has been on the New York Times bestseller list of Children's Series books for 48 weeks. Books in the series have also appeared on the USA Today, Publishers Weekly, and Wall Street Journal bestseller lists.
Critical reception of the 39 Clues has been mostly positive. The first book was met with positive reviews and spawned optimism for the rest of the series. The books have been very popular among kids.
Steven Spielberg acquired film rights to the series in June 2008. Spielberg and Scholastic Media president Deborah Forte will produce the series, while Brett Ratner expressed interest in directing the first film. Screenwriter Jeff Nathanson was hired to write the script in September 2008. In May 2012, Shawn Levy, the director of the Night at the Museum movies, acquired the rights to direct the movie. The movie, The 39 Clues: The Movie, is set to be released in early 2016. The movie rights were taken by Universal, in August 2013.
