Both a gripping locked room mystery, and a transporting, evocative portrait of a woman in crisis, Trouble Island marks the enthralling standalone suspense debut from Sharon Short, promising to be her breakout novel, inspired by a real island in Lake Erie, and true events from her own rich family history.

Madeline Brimley left small-town Georgia many years ago to go to college and pursue her dreams on the stage. Her dramatic escapades are many, but success has eluded her, leaving her at loose ends. But then she gets word that not only has her beloved, eccentric Aunt Rose passed, but she's left Madeline her equally eccentric bookstore housed in an old Victorian mansion in the small college town of Enigma. But when she arrives in her beat-up Fiat to claim The Old Juniper Bookstore—and restart her life—Madeline is faced with unexpected challenges.

Like any enterprising woman, Bea knows what she’s worth and is determined to get all she deserves—it just so happens that what she deserves is to marry rich. Filthy rich. After years of forced instruction by her mother in the art of swindling men, a now-solo Bea wants nothing more than to close and lock the door on their sordid partnership so she can disappear safely into old-money domesticity, sealing the final phase of her escape. When Bea chooses her ultimate target in the fully loaded, thoroughly dull and blue-blooded Collin Case, she’s ready to deploy all of her tricks one last time.

Jo Jones has always had a little trouble fitting in. As a neurodivergent, hyperlexic book editor and divorced New Yorker transplanted into the English countryside, Jo doesn’t know what stands out more: her Americanisms or her autism. After losing her job, her mother, and her marriage all in one year, she couldn’t be happier to take possession of a possibly haunted (and clearly unwanted) family estate in North Yorkshire. But when the body of the moody town groundskeeper turns up on her rug with three bullets in his back, Jo finds herself in potential danger—and she’s also a potential suspect.

After years of hustling, Collins Carter has finally made it...back to her parents’ house. Between tending to the compost with her newly retired dad and running into her high school nemesis at the only decent coffee shop in town, Collins realizes this subdivision from hell she swore she’d never return to is her rock bottom. Then the homeowner’s association complaint arrived.
