See Me, Cover Me — Barbara Gee

Book 4 of the "Full Heart Ranch" series -- Can be read as a stand-alone book, but reading books 1-3 will help with the back-story. No cliff-hanger. (The final book in the series will be released in March, 2017.)

Tanner James barely remembers who he was before joining the FBI a dozen years ago, and he's okay with that. Life-threatening assignments tend to change a person, and he's learned to become whoever he needs to be in order to handle danger and succeed in the tasks he's given. Since there's no one to miss the old Tanner, it's all working out--until his boss decides he needs to take some time off.

One look into the cold dark eyes of the new volunteer at the veterans retreat center has Izzy Harding plotting ways to lighten the man's burdens, whatever they might be. Turns out that's not a job for the faint-hearted. Tanner wants to keep to himself, just doing his thing and staying safe behind the walls he's built up to ward off people like her. Not gonna happen.....Izzy's determined to be his friend, and she's not easily put off. He needs to relax and enjoy life a little, and God-willing she's going to help him do it.

There are so many reasons why he should resist her efforts, but the girl is getting past his defenses. She says God is in control, but why would He care? Tanner knows he needs to pull back before she gets hurt. He has another job coming up and he doesn't need the distraction. But darkness craves light, and he craves Izzy.

He can't stay. She has to let him leave. Only God knows how it will end.
