The Inmate: From by Freida McFadden -Paperback

A gripping, twisty thriller from Freida McFadden, the Sunday Times bestselling author of The Housemaid and The Coworker! The guiltiest people aren't always the ones behind bars… As a new nurse practitioner at a maximum-security prison, Brooke Sullivan is taught three crucial rules:

But nobody knows that Brooke has already broken the rules. Nobody knows about her intimate connection to Shane Nelson, one of the penitentiary's most notorious and dangerous inmates. They certainly don't know that Shane was Brooke's high school sweetheart―the star quarterback, the golden boy who's serving a life sentence for a series of grisly murders. Or that Brooke's testimony was what put him there. But Shane knows. He knows more than anyone. And he will never forget. The Inmate is a propulsive, mind-bending thriller about how we define guilt―and who has to pay for it, from Sunday Times bestselling author Freida McFadden.
