Jane Peters is an adrift twenty-something by day, and a world-weary agony aunt by night. But when an office party goes too far, Jane dissolves into the high-stakes world of being the Other Woman: a role she has the right advice for, but not the smarts to follow through on. What starts out as a drunken mistake quickly unravels as Jane discovers that sex and power go hand-in-hand, and that it's hard to keep your head when you've become someone else's dirty little secret.
