Reputation : a novel / Sara Shepard.

"Aldrich University is rocked to its core with scandal and intrigue when a hacker dumps 40,000 people's emails--the entire faculty, staff, students, alums--onto an easily searchable database. Affairs and scandals immediately start leaking, but these emails become ticking time bombs that explode when Kit Manning's handsome husband, Dr. Greg Strasser, is murdered. Kit's sister, Willa, flies home to help, returning to a hometown she fled fifteen years ago...after a night she wishes she could forget. Willa, an investigative reporter, knows something is not quite right and is determined to find the truth--of what happened the night Greg was murdered, and of the secrets that are hiding in every house in town. With a killer on the loose, and families breaking apart seemingly by the minute, Willa and Kit have to figure out who killed Greg before the body count starts to rise."-- Publisher's description.
