When guests start dying in mysterious accidents at an exclusive underwater resort, Frankie Styles and her cyvlossic partner Spike go undercover to save the next victim.

Posing as eccentric heiress Evelyn Crowe and her "comfort animal" Precious, Frankie must navigate a weekend of ultra-wealthy guests who seem disturbingly unbothered by tragedy, a resort owner who controls every detail, and a young woman marked for death. With less than 48 hours before the next "accident," Frankie needs to figure out who she can trust in a place where nothing—and no one—is quite what they seem.

Perfect for fans of Becky Chambers' Wayfarers and T. Kingfisher's Paladin series—readers who love twisty mysteries with heart, humor, and hope in unexpected places.
