Best of #BookTok: A world-class diver risks everything for the men she left behind in this pulse-pounding romance from the New York Times–bestselling author of Den of Vipers.

Three years ago, deep-sea diver Peyton ran away from her chosen family—all fellow divers—Tyler, the first man she ever loved; his brother, Kalen; and his best friends, Riggs and Fin. All it took was one summer for her to fall hard and not just for Tyler. When he proposed, Peyton’s guilt forced her to flee as fast as her legs could carry her. She desperately wanted to say yes, but how could Tyler ever forgive her if he found out the truth: she was in love with all of them.

Leaving just about broke her, and to move on, Peyton poured everything she had into her work. Now one of the world’s best divers, she puts herself in danger’s path time and time again, exploring never-before-seen underwater caves. The thrill of the job is the only thing that makes her feel alive. That is, until her next diving assignment forces her to face the men who were once her whole life. Their anger toward her is an unmistakable force, but soon, long-buried emotions and desires come rushing back.

Despite the love, hate, and lust warring inside her, Peyton is determined to keep things professional on this dive. But down below, things can go wrong dangerously fast. When they find themselves trapped together within an elaborate system of caves, Peyton, Tyler, Kalen, Riggs, and Fin must confront the depths of their entanglements as they navigate their way to safety.

This edition features a bonus scene, character art, and a signed letter from the author.
