This is book 2 in The Cosantóir (Protectors) Series.
 
Cillian Meehan has lived the life of a loner for a long time. Called Preacher by the members of the motorcycle club the Cosantoir, Cillian has always been the moral center, trying to do what's right over the years, even in times where things might go wrong. What few of his brothers know is about his past with the priesthood, a passion early in his life that he abandoned for reasons he does not like to share. Only when the one woman he has ever had feelings for re-enters his life that old feelings and hardships are stirred up. Does Preacher have faith in himself to follow his heart?
