Neither know that the town is the site of a war between a really nasty pack of werewolves and other kinds of shapeshifters. As in "Wildest Dreams," there's a herd of deer shapeshifters -- the same herd, actually. Mason finds out the hard way that werewolves exist. Actually, I don't know if there is an easy way, but this was definitely a hard way.
I enjoyed the world-building, the protagonists, and their supporting characters. I'll probably get more of Emily Veinglory's books, depending on the subject matter. She has a long series that has elves in it.
