In Broad Daylight by Seth Harwood

FBI Agent Jess Harding always gets her man... or woman. In this thriller, Harding returns to the scene of her first years as an FBI agent to track the still-at-large killer from her first case. Back in 2006, as a young, inexperienced agent, Harding chased leads across Alaska for a full summer without catching up with this killer. Now, after 5 years of honing her skills, she's back and ready to try again. But when she starts to see that the killer knows a little something about her, the heat turns up and Harding realizes she may not be the only one getting chased.
