It appears he has amnesia and no idea who he is. But she does. He is Sir Simon, one of the Legion's top spies. Once upon a time, she fancied herself half in love with him, until he cruelly cut her in front of the ton.   Tempting as it is to leave him in the ditch where he was discovered, she takes Sir Simon in to care for him, realizing this is her chance to make him suffer as much as she has. She'll pretend he is a stranger to her until he has recovered his memory, and then she will deliver the punishment he so surely deserves. However, as Simon convalesces, Athena finds herself falling for him all over again.
But unless his memory fully returns and she can discover why he did what he did that traumatic night six years ago, she cannot risk her heart.
