Two girls whose lives couldn’t be more different are brought together as pen pals in this riveting and haunting novel that’s perfect for fans of Orange is the New Black and those interested in unpacking the reality of life behind bars.   Mandy and Tracey have never met, but they know everything about each other. Connected through a pen-pal ad, they exchange frequent letters, writing about boyfriends, siblings, music, and friends. They trade stories about school and home. They confide their worries and hopes. It almost makes it easier, and more special, that they’ve never met—they can say whatever they want in the safety of their private world of letters.   But that private world may not be as safe as it seems. Can Mandy trust Tracey to be who she says she is? What secrets hide between the lines of their letters?   "A powerful book. . . .
