The Mandie books are a children's historical mystery series written by Lois Gladys Leppard from 1983 to 2006, intended for children ages 8–12 years old. More than seven million copies have been printed of the Mandie series. There are forty books in the main series along with several special books. The setting of the series is North Carolina in the early 20th century. The story starts around the year 1900, when Mandie is 11 years old. In every book she finds a mystery to solve along with her good friends Joe Woodard and Celia Hamilton.
Mandie's full name is Amanda Elizabeth Shaw. She was born on June 6, 1888 and grew up in a log cabin in Swain County, North Carolina, with her beloved father Jim Shaw, her stepmother Etta, and her stepsister Irene in this slight adaptation to the Cinderella fairy tale. Mandie knew nothing about her family background until her father died. Mandie was soon sent away to live with the Brysons, a racist family, to take care of their new baby son named Andrew. Then her father's Cherokee best friend Ned Sweetwater came to take her away from her overbearing stepmother and the family who treated her cruelly. Mandie, Uncle Ned, and several Cherokee warriors escorted Mandie to the home of her rich uncle John Shaw, who Mandie had never heard about before.
Mandie is soon reunited with her birth mother, Elizabeth, in Macon County, North Carolina, in a town called Franklin, North Carolina, and learns the truth about her history. Mandie's paternal grandmother was Cherokee. Mandie meets many new friends among the Cherokee people. On one occasion she finds a cave with gold that belonged to a Cherokee warrior, Tsali. In 1901, Mandie goes to a girl's boarding school in Asheville, North Carolina. The school is strict, but Mandie does not care about bending the rules when there is a mystery to solve.
In College Days, Mandie and her friends attend college at College of Charleston Ladies' College in Charleston, South Carolina, where Mandie majors in business administration while Celia majors in music, and both minor in English literature and visual art.
The Mandie books are Christian in theme. Mandie prays when troubled, and attempts to demonstrate Christian virtues of tolerance and compassion. Mandie is proud to be part Cherokee, and she has a diverse group of friends, including a girl with mental retardation. Some critics have noted that the Cherokee and African American characters are at times depicted sentimentally and as speaking in a stereotypical dialect (for instance, Uncle Ned's speech is filled with terms like "happy hunting grounds", "squaw", and "papoose"). 
Author Lois Gladys Leppard was a Federal Civil Service employee in various countries around the world. She made her home in South Carolina. Leppard died October 5, 2008. Stories of her own mother's childhood are the basis for many of the incidents incorporated in this series.

- Amanda Elizabeth Shaw - Referred to as Mandie by her peers, Mandie enjoys solving mysteries, no matter how mysterious or dangerous the situation may be. She has long blond hair (usually braided), blue eyes, and is said to be quite short by her lifetime friend Joe, though that simply may be just his opinion, for he shoots up quite a bit throughout the series, but it is mentioned in 'Mandie and Fiery Rescue' that she is short for her age. Her favorite color is assumed to be blue. Mandie is a Christian, who stands up for her beliefs and values, though seems to vary from 'honor thy father and thy mother', as she is constantly running off and disobeying her parents. She is quite emotional and gets frustrated when she can't solve a mystery. Mandie longs to grow up throughout the series. Being raised in a log cabin with little more to her name than two hand-me-down dresses and a kitten, she sees everything simply and takes no interest in high society. When sent to a young ladies school to learn social graces, she finds it ridiculous and remains her own lively self. The death of her biological father affects her deeply, leading her to her Uncle John's resulting in the truth as to her biological mother with whom she is reunited. She becomes very attached to her mother who married her Uncle John. Her favorite verse is "What time I am afraid I will put my trust in Thee." Mandie, in most instances has a teachable spirit and will break into tears and ask for forgiveness if convicted, however occasionally she becomes stubbornly jealous of Joe or of her mother's attention and is immovable in her opinions. Sometimes, Mandie tells others that she will not get married, as she will be too busy when she grows older, and she doesn't want to become trapped at home, unlike many of the girls of her time. This assumption clearly irritates Joe, as he obviously likes Mandie, and reminds her every now and then he plans on marrying her. At times, Mandie seems interested in boys, but tends to avoid the topic, even with her best friend Celia. Mandie doesn't give in easily, and sometimes wants to do the jobs that a boy would do, like learning how to use a gun. In the first two movies, Mandie has brown eyes, but in the third, she has blue.
- Joseph Woodard - Known as Joe by almost everyone, he is Mandie's best friend. He has unruly brown hair, brown eyes, and long legs according to Mandie. Being Mandie's only friend who knew her father Jim Shaw (excluding relatives), Joe and Mandie are very close. Because Joe remains living in Swain County after Mandie moves away to Franklin, he promises to care for her father's grave and put flowers there. Joe is a country boy who does not care for much fancy things or money, but is a true friend. He intends on marrying her when he gets her father's property back from her step mother, Etta. He intends on doing this by becoming an attorney at law. He is very jealous when Mandie goes off to visit other male friends, such as Tommy Patton and Jonathan Guyer. He also helps Mandie on solving mysteries, but says that she does most of the work. He loves chocolate cake and is constantly joking around. Joe's father, Dr. Woodard is the local doctor in Mandie's area. Joe has a crush on Mandie, towards the end he tells Mandie he loves her.
