Esther has always been singular, set apart, different. She's a finder of words, a keeper of lost things. When an opportunity arises to work for one of the world's most elite espionage teams, she'd be a fool not to take a leap, even if it puts her life in danger.

Once a marine, now a spy, Leo is lost, broken, burned out. When he's assigned to guard a civilian no one else wants, he knows his career has hit rock bottom. Esther is like no one he's ever met, but it's those differences that begin to unlock something in Leo. When someone tries to take Esther out on Leo's watch, forcing Leo and Esther to depend on each other for everything, it soon becomes unclear who is lost and and who is in more need of being found.
