The 39 Clues is a series of adventure novels written by a collaboration of authors, including Rick Riordan, Gordon Korman, Peter Lerangis, Jude Watson, Patrick Carman, Linda Sue Park, Margaret Peterson Haddix, Roland Smith, David Baldacci, Jeff Hirsch, and Natalie Standiford. It will consist of five series, The Clue Hunt, Cahills vs. Vespers, Unstoppable, Doublecross, and The Rise of the Super Branch. They chronicle the adventures of two siblings, Amy and Dan Cahill, who discover that their family, the Cahills, has been the most influential family in history. The first story arc concerns Dan and Amy's quest to find the 39 Clues, which are ingredients to a serum that can create the most powerful person on Earth.[1] This series' primary audience is age 8–12.[citation needed] Since the release of the first novel, The Maze of Bones, on September 9, 2008, the books have gained popularity, positive reception, and commercial success. As of July 2010, the book series has about 8.5 million copies in print and has been translated into 24 languages.[2] The publisher of the books is Scholastic Press in the United States. Steven Spielberg acquired film rights to the series in June 2008, and a film based on the books will be released in 2016.[3] The series also originated tie-in merchandise, including collectible cards and an interactive Internet game.

The Clue Hunt[edit]

The 39 Clues books and card packs as of August 2010.
The path Amy and Dan took in the first ten books.

The first series revolves around Amy and Dan Cahill, orphans who upon their grandmother's death discover that the Cahill family has shaped most of world history. The ancestors of the family are Gideon and Olivia Cahill, whose children (Luke, Jane, Katherine, Thomas, and Madeline) created the branches of the family (Lucian, Janus, Ekaterina, Tomas, and Madrigal). The branches compete against each other in a hunt for the 39 Clues, ingredients to a serum, the source of the family's power. 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 the other branches. The books also contain the perspectives of the other Cahills as their views of Amy and Dan change. The environment all of the authors have created is an alternative reality in which influential historical figures 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.

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, former KGB agent, Irina Spasky. Pursuing clues hidden in Grace's library lead to a near death encounter. They had enough information to know to go to the Franklin Institute, there, Dan and Amy discover that Benjamin Franklin has hidden a clue in Paris.

A King's Ransom is the second book in the series. It was written by Jude Watson and published on December 6, 2011.

Amy and Dan are 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. 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 by hiding inside luggage bags and disembark at Enderberg. They disguise themselves as rich heirs to enter an auction house in Lucerne, then 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.

Later, William McIntyre meets Amy and Dan, 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 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.

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. 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 explains how Arthur was initiated into the Vespers but later cut off 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, who decide to help the siblings. Inside, Katja Mavel, the director of the library, gives them what they want. They find the map inside the book. 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. 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, but it goes wrong when Atticus follows them and is kidnapped. Vesper One now knows Dan and Amy have been hiding Marco Polo's epilogue 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.

The 39 Clues uses collectible cards in order to expand readers' experience of the series.[citation needed] 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.

In the fourth series Doublecross, each book will contain six virtual cards.

Overall, the cards form a key part of the series.[citation needed] 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 solve.

Additional cards have been released over the course of the series, and the cards are only virtual. Scholastic developed a game involving the cards, Doublecross, in which players physically use their cards to battle their opponents.

Themes[edit]

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.[21] 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.[17]

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.[22]

Origins[edit]

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.[23] Riordan agreed because he thought it was a good idea, and as a middle school teacher, he loved making history enjoyable for younger readers.[24][25] The project was kept secret for about two years.[26]

Reception[edit]

Awards[edit]

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.[27] Books in the series have also appeared on the USA Today, Publishers Weekly, and Wall Street Journal bestseller lists.[17]

Critical reception[edit]

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.[citation needed]

Film[edit]

Steven Spielberg acquired film rights to the series in June 2008. Spielberg and Scholastic Media president Deborah Forte will produce the series,[28] while Brett Ratner expressed interest in directing the first film. Screenwriter Jeff Nathanson was hired to write the script in September 2008.[29] In May 2012, Shawn Levy, the director of the Night at the Museum movies, acquired the rights to direct the movie.[30] The movie, The 39 Clues: The Movie, is set to be released in August 2018.[3][31][32][not in citations given] The movie rights were taken by Universal, in August 2013.[33]
