The Mandie books are a children's historical mystery series written by Lois Gladys Leppard, intended for children aged 8 to 12. Since the publication of the first book in 1983, more than seven million copies have been printed of the Mandie series. There are forty novels in the main series and eight in the junior 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 with her good friends Joe Woodard and Celia Hamilton.
The main character's full name is Amanda Elizabeth Shaw. Her birth date is given as June 6, 1888. She grew up in a log cabin in Swain County, North Carolina, with her beloved father Jim Shaw, her stepmother Etta, and her stepsister Irene. Mandie knew nothing about her family background until her father died. Mandie was soon sent away to live with the Brysons 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 the last published novel, New Horizons (2006), 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. New Horizons is called "Book One" of the Mandie: Her College Days series, but was the only one to be published before the author's death.
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.
