Shy and serious by day—insatiable by night.

Betrayed and abandoned by her first lover, shy and studious Miranda Cahill freezes in response to any sexual attention from someone she knows and likes.

During the day, she works diligently on her doctoral thesis. At night, though, she finds herself drawn into increasingly extreme sexual encounters with strangers. Her anonymous secret life begins to take over when she discovers that the masked seducer she meets in a sex club and the charismatic young professor courting her are the same man.
