The worst scars are hidden . . . For years, Sara served the shadowy Agency, until a mission gone wrong left her wounded, both physically and emotionally. Haunted by scars, Sara is counting down the days to her reconstructive surgery, the final step towards freedom from the Agency's clutches. Just as she's close to escaping it all, Sara's path crosses with Beckett, an uptight English professor with the uncanny ability to delve into people's minds with a mere touch. Anyone's mind except Sara's. Unbeknownst to her, Beckett is a member of a clandestine society of memory magicians, and he sees in Sara the perfect instrument to catapult his career within their ranks. Sara and Beckett clash fiercely, both determined to follow their own paths. But the Agency's grip on Sara is tighter than she realized, and they give her one more assignment: work for Beckett and his program to help budding memory magicians. And report back all the details. While forced to work side by side, Sara and Beckett soon discover that first impressions can be misleading, and animosity can easily transform into something altogether unexpected-an intoxicating mix of frustration and fascination. As the lines blur between loyalty and self-preservation, Sara finds herself torn between protecting Beckett and his students or safeguarding her own precarious freedom.  Will Sara's immunity be her salvation or her downfall? Can she navigate the treacherous landscape of spies and memory magic while protecting her heart?
