To hunt a killer in paradise, Sofia Costa must use every skill Interpol ever taught her—and stop a murderer who’s been watching from the start. Sofia Costa is no ordinary investigator. A former Interpol forensic polyglot turned luxury travel security consultant, she’s brilliant, solitary, and trained to blend in anywhere. When a discreet message summons her to the legendary Hotel Miramare high above the Amalfi Coast, she expects a petty theft. What she finds is far more sinister. Priceless heirlooms are being returned as if the thieves had a change of heart. A young woman is found dead in the infinity pool. And every guest—from billionaires to art collectors—has something to hide. As secrets surface and old ghosts stir, Sofia must outwit a killer hiding in paradise, navigate tangled histories, and confront the one mystery she’s never solved: her own. Lush, gripping, and atmospheric, The Drowning Season is the first book in the Sofia Costa mystery series—perfect for fans of Ruth Ware, Tana French, and Elle Gray.
