But when she uncovers evidence suggesting their deaths were no accident, grief gives way to resolve—and fear. Her search for the truth leads her to Graystone Island, an isolated community shrouded in secrets, where danger lurks beneath every calm smile and every crashing wave.

Donovan Jones, the man she once loved years ago—the one who disappeared without a word. Now a covert operative working deep undercover, Donovan has his own reasons for keeping his identity hidden. But when River’s investigation threatens to expose more than she realizes, Donovan is forced out of the shadows to protect her, even if it means endangering his mission.

As they navigate the perilous web of lies surrounding Graystone Island, old emotions resurface, blurring the line between trust and betrayal. Together, they uncover fragments of a conspiracy tied to a weapon of unimaginable power and a cover-up reaching the highest levels of authority.

To expose the truth, River must confront not only the darkness that destroyed her family—but also the man who broke her heart and the secrets he still keeps. Because on Graystone Island, nothing is what it seems—and some secrets are worth killing for.
