It's cold and a little lonely in the frozen north as 17- year-old Jermyn Graves continues his education as a spellmaker (he began it in A Plague of Sorcerers, 1991). Not even pretty Brianne, grandaughter of his magic mistress Lady Jean Allons, or Jermyn's own dainty skunk-familiar Delia can dispel the gloom- -particularly when it appears that the backlash from one of Jermyn's own spells is responsible for Lady Jean's death. Still, despite human hostility, a mysterious hedgewitch, and a surfeit of bad magic, Jermyn is able to unmask the true culprit and become a full-fledged spellmaker. Fast-moving, expertly written, and altogether charming. (Fiction. 10+)
