With her oldest sister married and her youngest sister celebrating her betrothal, most predict that Lady Tabitha Bartley, the bookish, plain sister, is doomed to be left on the shelf. She has seldom been noticed by the town until several bored gentlemen make an innocent wager regarding her and the Earl of Sterling Court. Lady Tabitha overhears their conversation and decides to beat them at their own game. But she will take it a step further and seduce Lord Sterling. She has read all about seduction from the books in her father's library. Since she doesn't expect to marry, this is probably her only chance to have a tantalizing sexual encounter. First, she must win the original wager and then make one of her own. Will Lord Sterling accept her challenge? What will be the prize for winning? And more importantly, can a lady seduce a gentleman and still be considered a lady?
