Author Cashman's bestselling debut novel,
The Truth About Horses, is the winner of the Independent Book Publishers Association's (IBPA) 2024 Benjamin Franklin Gold Award for General Fiction as well as its 2024 Silver Awards for Best New Voice and Teen Fiction.
The Truth About Horses tells the story of fourteen-year-old Reese Tucker, who is racing against time to save her injured horse, a struggling barn, and her shattered relationship with her father. The book's drama, humor, and realism—both magical and gritty—speak powerfully to the realities of heartbreak, grief, and recovery. Cashman launched the book in Dublin in 2023. She and
Jane Seymour are co-producing the film adaptation. In addition to
The Truth About Horses, Cashman has published two children's books,
The Not-So-Average Monkey of Kilkea Castle and ''Petri's Next Things''.
