Luis has spent his career chasing the darker side of life. First a vice cop, then an FBI profiler, now he lands in the Boston field office, and not by choice. He expects his case load to have a much lighter tone than he's used to. He wasn't counting on New England's dark history, or their pride in it. He didn't understand how close-knit the old towns could be, or how protective they were of their own. He soon finds he's going to have to count on every skill he ever used in his time at headquarters, and a few skills he didn't know he had, if he wants to keep body and soul together. Complicating matters is a new case Luis has just been handed, working with the Mass. State Police. Luis has history there, and ugly history too. Detective Donovan Carey is the guy who broke Luis' heart over a decade ago. He wasn't willing to even peek his head outside the closet, certainly not for someone like Luis. Can they put their history aside to deal with a mystery centuries in the making?
