Priest

Priest is the 1st book in the Priest Series.

He's a priest, and here is his confession.
 

There are many rules a priest can’t break. A priest cannot marry. A priest cannot abandon his flock. A priest cannot forsake his God. Tyler Bell has had no problem playing by the rules for the past three years after a family tragedy set him on the path to priesthood. That all changes when the delicious, sultry voice of Poppy Danforth sinks its claws in him through the screen of his confessional booth, and he can’t get her sins out of his head.
 

It should be easy to put his impure thoughts of her to rest, considering the vows Tyler has taken. It should be nothing to overcome what the sight and sound of her does to him, when his life with the Church means everything. But once he has his first forbidden taste of those red lips, Tyler can’t help but break all his rules for Poppy-no matter what it might cost them both.
