Thorn St. Croix is a stone mage who once saved the lives of the residents of Mineral City. As their savior, she has been partially accepted into their society. Yet, live cannot remain on an even keel.

First, the society of Mages has sent an emissary whose purpose in coming is cloaked in mystery. Second, she has to contend with a Dragon whos bonds have been loosened and again threatens the city she defends. Third, some of the humans she defends are beginning to change. No longer human, not mage and not quite seraph, Thorn will have to save her city from an evil that eclipses what they encountered the last time she saved them.

The story is set in a small town that has barely survived the devastation of the fight between a fallen seraph and those who wanted to destroy him. Mineral City is caught in an ice age which causes the city to have very few amenities for its residents. Thorn likes the life she has established here and doesn't like to have it threatened once again.

This was a rather confusing tale that had the seraphs and cherubim of the Lord still active in a land that has managed to bind the devil after many battles and the loss of thousands of lives. Thorn is caught in a situation where she doesn't know if she is being used or is actively leading the fight that Mineral City faces once again. She is forced to make decisions without a complete knowledge of the situation and without the training she should have received as a mage.

Fans of dark urban fantasy will enjoy the atmosphere and continuing battle between good and evil.
