Everyone knows the Byron brothers are "mad, bad, and dangerous." But the devilishly desirable fourth son, Drake, is too scholarly to misbehave . . . or is he? Lord Drake Byron has no time in his busy life to worry about taking a wife. He is more interested in the unbreakable code he has developed to defeat Napoleon's forces. Little does he know that the 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 to save her family, she embarks on a mission that takes an even more dangerous turn when she falls in love with the surprisingly tempting man she must ultimately betray. And if she succeeds in her mission, will she also break Lord Drake's heart, while leaving her own behind?
