A Good Morning America featured thriller, 2021 People magazine "Best Books of Summer" winner and a Good Housekeeping "Best Beach Read to Add to Your Summer Reading List" From Katherine St. John, author of The Lion's Den, comes a "reading experience that’s as layered and decadent as a slice of tiramisu" about a Hollywood heartthrob, his co-star ex-wife, and a film set on an isolated island that will unearth long-buried secrets—and unravel years of lies (Emily Henry, NYT bestselling author of People We Meet on Vacation, New York Times Book Review). In the midst of a sizzling hot summer, some of Hollywood's most notorious faces are assembled on the idyllic Caribbean island of St. Genesius to film The Siren, starring dangerously handsome megastar Cole Power playing opposite his ex-wife, Stella Rivers. The surefire blockbuster promises to entice audiences with its sultry storyline and intimately connected cast. Three very different women arrive on set, each with her own motive. Stella, an infamously unstable actress, is struggling to reclaim the career she lost in the wake of multiple, very public breakdowns. Taylor, a fledgling producer, is anxious to work on a film she hopes will turn her career around after her last job ended in scandal. And Felicity, Stella's mysterious new assistant, harbors designs of her own that threaten to upend everyone's plans. With a hurricane brewing offshore, each woman finds herself trapped on the island, united against a common enemy. But as deceptions come to light, misplaced trust may prove more perilous than the storm itself. Includes a Reading Group Guide.
