Tyrone has walked—or swam—the Earth a lot of years. Most of that time he's spent alone. Working with dozens of other marine shifters at World of Aquatica finally brings him close to others that are sort of his kind—they're marine shifters, anyway. He works security, seeing as he can't be in an exhibit because, technically, his kind are supposed to be extinct. When he spots a skinny human shoplifting, he catches him...and realizes the man—Braylon—is his mate. Tyrone convinces his boss and alpha not to call the police. Instead, they give Braylon several shifts of cleaning the park as a sort of community service. During that time, Tyrone has to go about doing something he hasn't had to do in over four hundred years of life. Can he figure out how to woo a human so very different from himself?
