Now before I start this review, this dude cheats, and when he does it, it rips your freaking soul out. 
 Shepherd manipulates Claire's instincts. 
 Forced pregnancy 
 Cages her 
 Punishes her 
 So cheating, while I almost flipped the table, it should not have been surprising. Even the way it happened shouldn't have been much of a shock. 
 Which goes to show the author not only fooled Claire into a false sense of security, but the reader too. 
 Shepherd isn't some knight and shining armor, this dude is pure evil. He will use what tool necessary to get what he wants. He wanted Claire's submission and loyalty. 
 My thoughts are below, and might be a spoiler, but if the cheating is preventing you my thoughts are below. 
 (view spoiler)[I can't say for certain if he has "real" feelings for Claire, but I can say the Cheating incident was to punish Claire. No matter what Shepherd did he couldn't get her full submission. He wanted to break her, and show her that I can do anything and still have you, Well that backfired. He did that exact opposite which broke the trance Claire seem to be in. Which calmed my frayed nerves. (hide spoiler)] 
 So why 3 stars. 
 What are omega and alphas, and betas? Are they shifters? I'm confused. 
 Lastly, I hate too many point of views.
