20 New Thrillers and Mystery Novels That Will Freak You Out This Fall

Can't sleep? When the Lights Go Out by Mary Kubica will be your perfect companion, since it centers around a young woman, Jessie, suffering from chronic, near-debilitating insomnia. When Jessie's sleepless nights begin hampering her life during daylight hours — her judgment is blurred, she can no longer tell the difference between what's real and what isn't — she finds herself with a lot more on her plate than simply a bizarre, 20-year-old mystery that has suddenly changed everything she's ever known.
