Dragonblaster: Book 5 of the Chronicles Grim Dragonblaster

As Mage Questor Grimm Afelnor continues his Quest to destroy the pernicious influence of the witch-nun, Lizaveta, he has no idea that the evil Prioress' inner coterie has abducted his secret lover, Drexelica. While Drex fights to retain her individuality in the face of relentless, savage torment, Grimm has to face troubles of his own, including the sullen opposition of the unpredictable Questor, Guy Great Flame. When the members of Grimm's party find themselves marked for sacrifice and imprisoned in a fortress immune to even Questor magic, the young mage has to consider highly unorthodox tactics in order to survive. Meanwhile, Lizaveta is training a new recruit: a human weapon of her own with which to beguile and vanquish the young Weapon of the Guild.
