This picks up after the events of Fair Game. Mercy is out Christmas shopping on Black Friday with her step-daughter Jesse. Mercy's beloved Rabbit gets totaled. None of the pack answers when she calls. They've been kidnapped.
This one was so much better than River Marked (thus far my least favorite). This one picks up full steam ahead. I liked the who-done-it. But, I thought it could have been a little more suspenseful. Jesse and the Sandovals disappear after a certain point. The mystery is still out there how the mercenaries were able to get their hands on so much of the formula that does, very effectively, take down werewolves. Who else knows about the formula? I loved that Tad and Stefan (and briefly Zee) were in this one. Kyle also had a decent toll to play too.
One thing I wish were different: Mercy has people who, if not friends, are allies. But they are all men. The women in the pack (Honey and Mary Jo) don't like Mercy. Marsilia is a bitch. Ariana might be a possibility, but she's on the page briefly. That leaves Jesse. As much as I like Jesse, she's a teenager. Why can't Mercy have an adult female friend?
And this: Jesse's question to Mercy at the beginning on the book when they are out shopping. "When are you and Dad going to have a baby?" Mercy never had or got a chance to answer that. And I admit I'm curious.
