When Aimee comes home and discovers her husband is missing, she doesn't seem to know what to do or how to act. The police think she's hiding something and they're right, she is - but perhaps not what they thought. Aimee has a secret she's never shared, and yet, she suspects that someone knows. As she struggles to keep her career and sanity intact, her past comes back to haunt her in ways more dangerous than she could have ever imagined.

I Know Who You Are will leave your heart pounding and your pulse racing. This is the most twisted thriller you'll read all year.
