Surpassing its popular prequel Eragon , this second volume in the Inheritance trilogy shows growing maturity and skill on the part of its very young author, who was only seventeen when the first volume was published in 2003. The story is solidly in the tradition (some might say derivative) of the classic heroic quest fantasy, with the predictable cast of dwarves, elves, and dragons--but also including some imaginatively creepy creatures of evil.
