Publisher's Summary Augum, Bridget, and Leera want only to study new spells and make their legendary mentor proud. But when she unexpectedly departs on a crucial quest, they run afoul of a devious old witch and are forced to make a hasty getaway - straight into the hands of a notorious maniac known as the Blade of Sorrows.  Prisoners of the Blade and his sadistic apprentice, the trio must face its greatest challenge yet: escape using nothing but an ancient spell with some nasty side effects. But more than their lives are at stake, for an entire kingdom's hopes rest with their mentor - and she's heading for a deadly trap. ©2015 Sever Bronny Ltd. (P)2018 Skyboat Media, Inc.
