At the beginning of this fantasy from horror writer TIm Waggoner, everyone in the country of Athymar suddenly falls asleep. On awakening, most people have gained a minor magical ability (e.g., one man can change his eye color). "The Change" has a more significant effect on others, including Tarian Ambrus, a former soldier. Tarian is now a healer, but he can no longer hold a weapon. Tarian's wife, Lowri, suffers an even more unpleasant change. For Lowri's sake, Tarian. his son, Phelan, a royal wizard, a priestess-adviser to the queen of Athymar and an Eyslk (an elf type) go on a quest to find the source of the magic and somehow reverse it.

This is the first half of a story with kind of stock fantasy characters in a kind of stock fantasy quest adventure, but it has a few cool twists. All of the people in this world have been infected with a D&D version of the Wild Card virus; they've all been given some supernatural ability, sometimes beneficial, sometimes not so much. The main warrior character gets the ability to heal, but (a la Clockwork Orange) can no longer touch a weapon. His wife becomes something like a vampire demon, their son something like a werewolf, etc. etc.
Though not the first time I've seen the idea of "The Change", it is certainly one of the better executed, particularly in the fantasy genre. This book finishes rather abruptly, and so could not be called "stand-alone" resulting in the loss of a star.
