But when his incomplete body is deemed defective and dangerous, he’s cast aside as a failed product, discarded like broken porcelain. Before he can be sold off cheaply, a mysterious attack leaves him unconscious. When he wakes, he learns he’s already been bought, for a staggering sum, by an unknown master. His search for answers leads him to Dream Palace, a sprawling casino ruled by the enigmatic Jay, a man whose beauty and power are matched only by his madness.
