Ryan is a detective with the Abused Persons unit of the Mass. State Police. He loves his job, and he's very good at it. He balks when his supervisor assigns him to a case with the Cold Case unit, and not just because that's out of his area of expertise. Everyone in Cold Case is an alpha, and that's just not a comfortable place for an unclaimed omega to be. Nick is a detective with the Cold Case unit. He's a strictly by-the-book detective. He trusts to procedure and precedent to get the job done. He doesn't mind getting stuck with a highly visible case. He doesn't even mind getting stuck with the pretty omega from Abused Persons, so long as he sits down, shuts up and doesn't screw with the process that's worked well for years. Ryan and Nick butt heads almost immediately, although it doesn't take long for either detective to figure out that at least part of the reason for their strife is the scorching chemistry between them. When their cold case seems to parallel Ryan's life a little too closely, and when Ryan's methods don't fall exactly in line with Cold Case procedure, will their differences drive them apart?
