Brown University seems like the perfect place for the seventeen-year-old to forget her past. Hope for a normal life comes in the form of a handsome new running partner who makes her heart race and body perspire even before she laces up her shoes.
When her Russian professor gives her a puzzle that seems impossible to solve, Alex discovers that he has a secret - one that will catapult her into a world of cryptic codes and covert missions. As she tries to find a balance between the two different worlds vying for her attention, Alex wonders if she can have relationships with the ones she cares about while hiding a clandestine life, uncovering the truths of an underground enemy.
One thing is for certain, whatever happens will be forever etched into her memory. And some things are better left forgotten.
