Colton Martinez is a seahorse shifter and lives a comfortable life at World of Aquatica, a shifter owned and operated marine park. When a number of others find their Fate-given mates, he doesn't give finding his own much thought—until he scents the most alluring aroma in a big, handsome human named Waylon Davison. Discovering his mate has a boyfriend doesn't deter Colton. Instead, he lifts Waylon's wallet and, with the help of friends, plans his strategy for wooing the man. After learning his human is disturbingly cowed by his boyfriend, Colton realizes Waylon has more to overcome than the shock of discovering that shifters exist. Even if Colton can convince Waylon to dump his jerk of a boyfriend, can he convince his human that entering a pairing with a man chosen by Fate isn't a new prison?
