Bestselling true crime author Stella Sands turns her expertise in crime, language and human behavior into a twisted new mystery with CODEBREAKERS: A Wordhunter Mystery, a brain-teasing novel built around signs, symbols, linguistics and a truly unconventional detective.
Set in the swampy landscape of south-central Florida, CODEBREAKERS follows Maggie Moore, a foul-mouthed word genius whose extraordinary command of language makes her an unlikely but formidable investigator. Described by the publisher as a Lisbeth Salanderesque savant who could give Sherlock Holmes a run for his money, Maggie brings a distinctive combination of intelligence, attitude and unpredictability to the mystery.
The novel is the second installment in Sands’ Wordhunter series but can also be read as a standalone story, giving new readers an easy entry point. At the center of the book are multiple cases that challenge Maggie and her partner as they work through clues involving language, symbols and hidden meanings.
Sands’ background in true crime helped shape the novel. Drawing on decades of experience in the criminal world, she conducted extensive interviews while developing the story, speaking with forensic linguists, semiotic experts, tattoo artists, former cult members and a sentence diagramming expert.
That research gives CODEBREAKERS an unusual foundation for a mystery, particularly as Sands uses language itself as part of the investigation. Readers are invited to work through sentence diagrams, word puzzles and other clues alongside the characters, making the book as much a mental challenge as a traditional whodunit.
The novel also leans heavily into popular culture and literature. Famous book, movie and song references are woven throughout the story, adding another layer for readers who enjoy wordplay, literary clues and cultural references.
Early reviews have highlighted the book’s distinctive approach. Publishers Weekly called it “a satisfying whodunit,” praising Sands’ use of linguistic puzzles in the mystery plot, while Library Journal described Maggie as a brilliant savant and suggested the character could anchor a series of future Wordhunter mysteries.
Kirkus Reviews praised the partnership at the center of the story, while bestselling author Jenna Blum called CODEBREAKERS an addictive crime and buddy mystery centered on a powerful female character and “the power of words.”
Published by HarperCollins, CODEBREAKERS: A Wordhunter Mystery is scheduled for release August 11, 2026. With its combination of true crime research, linguistic puzzles, quirky characters and suspense, the novel offers a fresh take on the traditional mystery genre.
