Mercy and Adam get married and honeymoon at a campground with a new RV, where they battle bad fae otterkin and an evil Native American river monster. 
 Mercy meets her father (sort of) who died (sort of) about 32 years ago, before she was born. She also must confront Adam's wolf, when the wolf is in control. 
 A bit hokey -- all the Coyote legends -- but hey, it's fantasy. Also, I wanted to see more of Samuel and Ariana in this book, given how the prior book -- Silver Borne -- ended, and given that we have kept our fingers crossed for poor Sam for 5 books. Sadly, the couple was given no air time, and only mentioned as possible companions for Jessie while her dad and Mercy were on honeymoon.
