The black elfstone

The Four Lands has been at peace for generations, but now a mysterious army of invaders is cutting a bloody swath across a remote region of the land. No one knows who they are, where they come from, or what they are after - and most seem content to ignore these disturbing events. The only people who sense a greater, growing threat and wish to uncover the truth are society's outcasts: an exiled High Druid, a conflicted warrior, a teenage girl struggling to master a prodigious magic - and a scrappy young orphan, improbably named Shea Ohmsford.
