Rachel is still relatively new to the whole wolf thing, she still has nightmares about the event that activated her wolf DNA, it would give me nightmares too. They were getting better but ever since L.A. (the events in the last book) they have gotten worse and Rachel is afraid she's losing her mind because now she's started to see and hear things. It doesn't help that every so often she gets a delectable scent in the air that's gone as quickly as it appears.
Knox is known to make impulsive decisions, like joining the Navy, becoming a SEAL, leaving the Navy but his last impulsive decision put in hip deep in trouble by joining The Hunters. He believed their scare tactics it wasn't until his first mission with them that he regretted his rash decision because in the end he ended up as one of werewolves. He saved one by taking a bullet meant for her, she could have killed him but she let him go. He saw her again in L.A. and knew that if there was anyone her could talk to about what happened to him it would be her.
Two things happen in this book, aside from the smokin' hot romance between Rachel and Knox, The SWAT is put on protection duty of the DA whose life is being threatened because her most recent case. Her husband has also hired a private firm to handle security so SWAT will be working side by side with them bring together Rachel and Knox. Thankfully no one else knows about Knox being a former Hunter but Rachel and one other, but he isn't there right now. The other thing is that Rachel thinks she is losing her mind the crazed man who tried to kill her keeps appearing keeps talking to her. She agrees to help Knox learn who to be a wolf bringing them in even closer contact with each other, they feel safe with each other, trusting each other came easily. Knox knows about what happened and he wants to help but how can you protect someone from their own mind.
Overall, it is a great read. I loved Rachel and Knox. There aren't very many more of these guys left so I hope that means Tyler's introduction to the FBI special unit will lead to a spin-off series.
