Nul's Quest: Brad Strickland

Book II of Jeremy Moon/Thaumia. In Twilight Valley - where spells don't work at all - any wizard mad enough to admit his trade will find himself in front of a squad of archers. But Jeremy Moon, advertising executive turned sorcerer, has sworn to help his small furry friend Nul the Pika in his quest to find any surviving members of his almost-extinct race. Of course, the trail leads Jeremy, Nul and the wizard Barach - with sundry stone gargoyles - straight to the dangerous Twilight Valley. Cover art by Tony Roberts.
