They are London’s most scandalous couple.

Lady Isabel, Lady Pelham, and Gerard Faulkner, Marquess of Grayson, are well matched in all things – lusty appetites, constant paramours, provocative reputations, and their absolute refusal to ruin a marriage of convenience by falling in love.

When, four years later, Gerard returns, the boyish rogue is now a powerful, irresistible man determined to seduce Isabel. He is not the man she married – but is he the one to finally steal her heart?
