Bed and the Bachelor [EPUB ebook] 

A scholarly lord falls for an enemy spy in this Regency romance series finale “with plenty of red-hot lust and chilling danger” (Publishers Weekly). Lord Drake Byron has no time to worry about taking a wife. He is fully devoted to helping defeat Napoleon’s forces with the unbreakable code he developed. Little does he know that their irresistibly lovely new housekeeper he’s hired is really a French secret agent. Sebastianne Dumont is not at all who she seems to be. Forced to spy in order to save her family, she reluctantly embarks on her mission. And that mission becomes even more dangerous when she falls in love with the devilishly desirable man she must ultimately betray.
