Colton's Code Red by Tara Taylor Quinn

They’ll go to extremes to solve the crime until their partnership makes her the new target.

Following a string of recent arrests, Special Agent Jacob Colton is this close to exposing the human trafficking ring in Dark Canyon. But he needs Mae Copeland to close the case. The introverted, workaholic forensic scientist proves to be the ideal partner — as determined as he is to stop the rising body count. When he escorts her to a family wedding as a quid pro quo — their professional relationship starts to turn personal. Intimate. Primal. But when Mae is targeted by the traffickers herself, can Jacob stop the villains bent on thwarting their investigation...and keep her alive?
