The Devil in Disguise (Regency Rogues, #1)

Lord William Randall, the Duke of Clairemont, is a rake with little regard for society—a most unlikely suitor for Lady Lucinda Grey. But his latest assignment for the Young Corinthians, an elite spy organization, involves protecting her from a kidnapping plot. To do this, the notorious "Iron Will" must use his devilish charm to seduce Lucinda and convince her he's worthy of her attention. William never planned to become enthralled by the lovely Lady Grey—or to lose his own heart in the bargain.

Beautiful and fiercely intelligent, Lucinda has managed to gracefully sidestep even the most persistent suitors. Until the Duke of Clairemont, that is. She's tempted by his sinfully sensuous mouth and piercing eyes, and finds it hard to resist the champion thoroughbred he offers her in exchange for the honor of courting her. Can she keep him at arm's length when his touch begs her to let him so much closer?
