To the residents of Abalone, Arizona, a sleepy southwestern town whose chief concern is surviving the Great Depression, the arrival of a circus in town is a chance to forget their woes for a while. But this is the circus of Dr. Lao and instead of relief, the townsfolk are confronted with an array creature seemingly straight out of mythology: a chimera, a Medusa, a sphinx, a sea serpent and, of course, the elusive, ever-changing Dr. Lao. As the circus unfolds, it spins events towards a climactic final act that will change the lives of Abalone''s residents for ever.
