All the Wrong Places - Bluewater Bay, #6

Three cheating girlfriends in a row have given skateboarder Brennan Cross the same excuse: he wasn't meeting their needs. Desperate and humiliated, he goes to the professionals at the local sex shop for advice. Zafir Hamady, a sales clerk at Red Hot Bluewater, has an unusual theory: he doesn't think Brennan is a bad lover. In fact, he doesn't think Brennan is heterosexual. Or sexual at all, for that matter.
He also can't stop thinking about Brennan. But even if he's right and Brennan really is asexual, that doesn't mean Zafir has a chance. Brennan's never dated a man, and Zafir's never met anyone who's game for a Muslim single father with a smart mouth and a GED. Brennan's always thought of himself as straight. But when sex is explicitly out of the mix, he finds himself drawn to Zafir for the qualities and interests they share.
And Zafir can't help enjoying Brennan's company and the growing bond between Brennan and his son. They work well together, but with so many issues between them, doubts creep in, and Brennan's struggle with his identity could push away the one person he didn't know he could love.
