It struggled for that 3, much as I struggled to even get into it.
Our H/h, both shifters, and apparently mates, met way too young I think. He had family obligations, and she had the understanding of a gnat. She spent way too much time dwelling on his "letting her down" when she knew the family he was from to start with so what exactly did she expect him to do?
He took up drinking apparently because of this and was a nasty drunk. Enter mommy dearest who flat out tells him she has no feelings for her family, then disappears him for over 3 months where she experiments on him, then dumps him at the family compound. He eventually leaves and disappears for a bit, then after an apparent arrest attempt, finds himself shifting into a completely different animal.
Things that bug me... ah...most of the book? Nobody stopping to think maybe he had a tracker on him courtesy of his "loving" mother? Nobody ever stopping to consider the orphan might have come from the lab? Really, she could hide her scent. The h's attitude towards the H. The fact that we get a second round of some evil person experimenting on shifters. The lack of any real humor...
