My first thoughts on this book were that it was a bit formulaic and that the author had a very "young" female voice. Once I got a bit further though, I found myself really drawn in and annoyed at things that interrupted my reading time.
Lysandra, a blind healer with a type of mystical Sight, is called by prophecy to help the "Font of Wisdom". There to help here will be a her wolf companion and a country priest. But the sorceress Aurya and a bishop with his eye towards ecclesiastical power will be out to stop her and put Baron Giraldus (Aurya's lover) on the High King's throne.
There are some mixed messages here regarding religion and magic. Female deities and other non-Christian religions are clearly evil and practiced by witches. The same church says that practicing magic in any form is wrong and immoral. Yet the prophet who Lysandra keeps seeing and who wrote the prophecy that the 3 companions are struggling to fulfill seems to have magic, and magic used on their behalf will be key to their venture.
There is descriptions of sexuality and violence, and in the first few pages sexual violence is alluded to.
