Since moving into his new townhouse, Caleb has had fantasies about his gorgeous neighbor, Devin. When the two start seeing each other, Caleb can scarcely believe his good luck. He soon falls head over heels in love with the sweet, sexy ballet dancer. It seems nothing can drive them apart. Then one night Caleb kills a serial rapist in self defense and afterward is plagued by a voice in his head that stirs violent sexual cravings. Each night the cravings become almost unbearable and Caleb fears he is losing his mind. His attraction to Devin and the desires of the sex demon that has possessed him are a dangerous combination. To keep from attacking the man he loves, Caleb breaks off their relationship and buys a security cage with a time release lock. He spends each night inside the cage, consumed by a need to feed his sexual hunger. No one can understand his obsession, or so he thinks. Despite his seemingly happy life and gentle disposition, Devin fully understands obsession. After battling his own demons for years, he knows they can be beaten and he refuses to give up his lover without a fight.
