They were once orphans from London's roughest slums. Now they are students of Mrs. Merlin's Academy for Select Young Ladies, learning the art of spying and seduction. Bold, beautiful, and oh-so-dangerous, they are England's ultimate secret weapons. The most skilled of Merlin's Maidens, Siena must unmask a traitor lurking among an exclusive club of book collectors. Armed with only her wits, her blades, and her sultry body, she joins the gentlemen at a country house party. But her prime suspect, disgraced ex-army officer Lord Kirtland proves as enigmatic as he is suspicious-and sinfully sensuous. Kirtland's instincts tell him the enticing Black Dove is hiding more than a luscious body beneath her fancy silks. Yet as he starts to plumb her secrets, a cunning adversary lays plans to destroy them both. To live, Siena must end her tantalizing dance of deception and desire-and decide whether to trust her head or her heart.
