As the captain of Field County's ice rescue dive team, Callum Cook is driven to perfection. But when he meets new diver Louise "Lou" Sparks, all that hard-won order is obliterated in an instant. Lou is a hurricane. A walking disaster. And with her, he's never felt more alive . . . even if keeping her safe may just kill him.

Lou's new to the Rockies, intent on escaping her controlling ex, and she's determined to make it on her own terms . . . no matter how tempting Callum may be. But when a routine training exercise unearths a body, Lou and Callum find themselves thrust into a deadly game of cat and mouse with a killer who'll stop at nothing to silence Lou—and prove that not even her new Search and Rescue family can keep her safe forever.

Contains mature themes.
