Proper, reserved Francesca detests chaotic London and one of its most infamous inhabitants: her birth mother, the notorious courtesan Madame Aphrodite. Lovingly raised by the devoted Lady Greentree, she's content to remain in Yorkshire, far from the scandalous parent whose life and profession shock . . . yet intrigue her. But a dark, dangerous stranger she rescues on the moors is awakening a most improper desire—causing Francesca to question whether she is more her mother's daughter than she ever wished to be.

When Sebastian Thorne agrees to protect Aphrodite's estranged daughter from a dire threat emerging from her past, the fallen lord is unexpectedly seduced by Francesca's beauty. But a vigilante living on the shadowy edge of society has little hope to own such a prize—and unless he reclaims his abandoned title and lost honor, Sebastian will never get close enough to the bewitching lady to save her life . . . or win her passion.
