Everything Rami Ramirez holds dear is put in jeopardy when his past comes calling in the explosive series finale!

Trusting him might just put both their lives at risk.

Bryan “Rock” Rocovich hates to be in debt–in any shape or form. So, knowing that he owes Tessa Armstrong has left him more than a little itchy. After months of waiting for her to call him, he is relieved when she finally approaches him. Only, what she calls a simple research project turns out to be more than either of them bargained for.

Tessa knows what she is doing. Well, maybe. Granted she is more of an analyst than a rank and file FBI agent, but she has wanted to solve this case for decades. Her job with the FBI makes it hard for her to really dig, so she calls in that favor Rock owes her.

Once she reveals everything, Rock is worried that she might just be a little obsessed. He’s not sure there is even a serial killer to be found, until after a few close calls. Soon the two are on the run, drawing them even closer together.

Keeping both of them alive is easier than falling in love.
