Book four of this famous series of YA Fantasy books is a solid and highly entertaining adventure yarn for the young and old book lover alike.  Book three ended with the escape and apparent liberation of Will and Evanlyn from a life of drugs and slavery, respectively, and it is not long into this fine adventure story (book four) when they are finally blessed with some much needed personal success by reacquainting themselves with old friends.  And a highly emotional scene that is guaranteed to be for all concerned.
