I absolutely loved this book. It is the fourth book in this series, and in my opinion, it is the best. All the books in this series have been wonderful, but this one grabbed me from the first page. The story begins as Isabel finds Alec unconscious in the Alaskan wilderness. She manages to save his life, but has she risked her own life and safety by doing so? Immediately upon awakening, Alec (whose memory has been affected) accuses Isabel of being his attacker. This begins a back and forth attack and retreat between these two even as they fight the heavy pull of attraction they both feel. Isabel wants to uncover the plot that ended in her brother's death, and she believes Alec is behind the cover up. Alec insists he has been doing everything he can to help. Both retain their suspicions of each other.
Strange and dangerous things begin to happen. When Isabel is attacked with what appears to be two experimental weapons, Alec takes her back to the Raptor compound. He has been keeping her away, but it is the place where her brother died and the one place she wants to be. Unfortunately for her, once she is on the compound, the danger only escalates. Can she and Alec settle their differences and work together to find the weapons and the people wielding them, or is trying to work together only going to get them both killed?
This story was really well written and kept the action and suspense moving from the very beginning all the way until the end. The romance was also extremely sexy. Isabel was quirky and sassy with a soft insecure center. Alec was the " king tiger" in his domain. He was a total in charge alpha but with a devilishly charming way about him. I was completely enchanted by him. Characters from the previous books made appearances which added to the story for me. I am completely thrilled to have gotten a copy from Net Galley for review!
