Light of Eidon by Karen Hancock, a review

Abramm is calling himself Brother Eldrin, and all he wants is to be left alone by his family. But his family isn’t happy about it, not the least because it’s the royal family, and he’s now second in line to the throne. Soon Abramm discovers that the holy orders that have been his life for the past eight years are a front for evil people who want to use him as a puppet.
