The Fall of Shannara4 books in series
The Black Elfstone Publisher's Summary
The Black Elfstone is the first book in the Fall of Shannara, the epic four-part conclusion to the wildly popular Shannara series by Terry Brooks - one of the all-time masters of fantasy.
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.
