The Cautious Heart — Phillppa Heywood

Still a captivating beauty ten years after her own scandal-tainted season, Eleanor Portland returns to London. Facing down and finally dazzling the society that would shun her, Eleanor comes into her own. As a girl, she'd loved unwisely and borne the pain of a heart scarred by her faithless lover. Now, as a woman, she can withstand the barbs of sharp-tongued gossip, even the pursuit of a devastatingly attractive rake...or she thinks she can. But the sought-after, scandalous Lord Merriot is determined to have the wary lady who tries valiantly to put reason...before rapture.
