Meet the Blackthorn Brothers--three unrepentant scoundrels infamous for being mad, bad and perilous to love. Handsome as the devil and twice as tempting, Robin "Puck" Blackthorn lives for the pleasures of the moment. His only rule--never dally with an innocent woman. But when an encounter at a masquerade ball leaves him coveting the one woman who refuses to succumb to his charms, Puck realizes that some rules were made to be broken.... Scandalized to discover that the masked man with whom she'd shared a dance--and a forbidden embrace--is in fact the ton's most celebrated rake, Regina Hackett vows to keep her distance. Yet when her cousin vanishes, it is to Puck that Regina must turn. And as they embark on a dangerous journey through London's darkest alleys, Regina will discover that beneath Puck's roguish facade lies a man who will stop at nothing to protect her--or to convince her to take a chance on an unrepentant sinner.
