Thursdays aren't simply another day of the week for Amy Spencer and Ellis Hall. Thursday afternoons sizzle with no-strings sex for the two women, who meet each week in a hotel room to forget their past—and their present.

The arrangement works perfectly for Amy, a busy surgeon who's still smarting from a failed relationship. For Ellis, Thursday afternoons act as a pressure valve from her cutthroat job and the mistakes in her personal life she's trying to rectify.

But soon the pair discover that their outside worlds are on a collision course with the carefully constructed world they've created on Thursday afternoons. What will happen when they discover the truth about each other? Will their weekly assignations come to a screeching halt, or will they turn into something much, much more?
