Quint is a wizard and healer, and a dwarf, abandoned by his mother as an infant and tortured by his stunted, distorted body.

Drawn into a quest for the Torg and his own history, Quint and his apprentice are threatened by their companions, outlaws, the Great Wolves and the Torg. As the wizard confronts his origins, his world is shaken. Of all the dangers he faces his own heritage may be the most deadly.
