Coyote shifter Mercy Thompson knows that life with her mate, the Alpha werewolf Adam, will never be boring, but even their wedding doesn't go as planned. Nevertheless, a ten-day honeymoon camping on the banks of the Columbia River, alone, just the two of them, should make up for it. But the trip - and the pimped-out trailer they're using - is courtesy of the fae. And nothing from the fae comes without strings attached...
Being a different breed of shapeshifter - a walker - Mercy can see ghosts, but the spirit of her long-gone father has never visited her. Until now. An evil is stirring in the depths of the Columbia River - and innocent people are dying. As other walkers make their presence know to Mercy, she must reconnect with her heritage to exorcise the world of the legend known as the river devil.
Mercy and Adam finally get married. It is suppose to be in 6 weeks, but she ends up having a surprise wedding because of her mother pushing her.
On their honey moon Mercy and Adam help the local Indian tribe with some problems they are having. And Mercy meets more people who are like her, and even someone who might be related to her.
I really enjoyed this book. I loved getting to see more of Mercy and Adam together. And I loved finding out more about Mercy's heritage, and all of the cool walker gifts. This book has lots of different surprises as well, and Mercy's vampire friend is back in action finally.
