Lovely Catherine Miller has always been timid -- until the treachery of unscrupulous cousins threatens her childhood home. But her discovery of the journal of the notorious "Thief of Robinson Square" has given the resourceful lady a plan.

To exact a righteous vengeance, she will don the mantle of this "Robin Hood" who, years ago, preyed on pompous Society. She doesn't realize, however, that the one man in London sworn to stop her is the man she has loved in secret since she was twelve!

An important mission to unmask a traitor has brought Major Marcus Dunn back to Catherine Miller, only to find that the shy, awkward girl he remembers is now an enticing young woman with a spirit as strong as his. But the tempting enchantress guards a secret, and Marcus fears his desire for her could expose his own -- and send them both careening recklessly toward a passionate love far more perilous than mere scandal.
