What to read after Catlin's Appaloosa?

Detective Catlin Hill doesn�t understand the instant, possessive attraction he feels for the slender John Doe in the hospital bed. But the minute those scared baby blues meet his, Catlin lets his protective instincts rule him. The guy has amnesia, and it�s only from a conditioned response that Catlin confirms his name is Gallo Ricci. After passing the case to a fellow detective, he takes the victim home with him and gives in to lust. For some reason, it doesn�t even faze Catlin when his new lover turns into a horse in his living room. When a group of guys drop by and start talking about mates and centuries of living together, Gallo has a panic attack, proving his past abuse won�t allow him to take charge enough to claim Catlin. Is their relationship doomed from the start? And what�s tough enough to take down a shifter and leave him in the hospital?
