Esrever Doom
by Piers Anthony
In our Mundane world, Kody undergoes controlled coma, with possible side effect of Reverse Mood (title backwards). He wakes in Xanth, immune to curse that switches how people see each other, pretty as ugly, and vice versa. He likes zombie Zosi, starts double Quest, to break spell and save zombies. Team has unknowing spy for villainess NoAmi. Demons have wagers on outcome.
