March 14th, 2012 was a typical day for Emma Simpson, a successful portfolio manager running the Manhattan office of a big-time hedge fund. Emma followed her usual routine, interacting with coworkers and clients before returning to her quiet family home in the Hudson Valley, where she lives with her husband and two children.

But more than a year later, Emma's world is forever changed-all because of a short email she dashed off on her way home that day to simply support routine company practices. That email becomes the focal point of a criminal investigation by ambitious federal prosecutors.

Alexandra Shapiro's Presumed Guilty follows Emma's journey as the target of a federal white-collar criminal prosecution. She must now fight to prove her innocence, protect her family, and preserve her reputation.

Will she prevail, or will the justice system fail her?
