Unforgettable Faith by Michael Mandrake

Father Joseph deadened himself to love, but Diego refuses to give up on romancing the ornery priest.
After Joseph spent part of his life running from captivity, he found solace in church. The only thing stopping him from true serenity is reassembling the broken pieces of his past. Fragments that cause him mental anguish and bring him to his knees.
Diego’s travels lead him to Vale Valley to pitch a product, but when he prepares to leave, his wanton desire forces him to stay put. Despite not knowing what or why, Diego surrenders to his instincts.
Wolves and tigers aren’t supposed to be buddies, so why is the attraction between them irresistible? Will they remain together regardless of issues that could tear them apart?
