"Thriller fans, especially those who love One of Us Is Lying, will devour this page-turner."-Buzzfeed

No one at Hollywood High knows who's behind We'll Never Tell-a viral YouTube channel where the anonymous creators trespass behind the scenes of LA's most intriguing locales. The team includes CASEY, quiet researcher and trivia champ; JACOB, voice narrator and video editor, who is secretly dating EDDIE, aspiring filmmaker; and ZOE, coder and breaking-and-entering extraordinaire.

Now senior year is winding down, and with their lives heading in different directions, the YouTubers vow to go out with a bang. Their last episode will be filmed at the infamous Valentini "murder house," which has been left abandoned, bloodstained, and untouched since a shocking murder/suicide in 1972. When the teens break in, they capture epic footage. But someone trips an alarm, and it's a mad dash to get out before the police arrive-at which point they realize only three of them escaped instead of four. Jacob is still inside, slain and bleeding out. Is his attack connected to the historic murder, or is one of their crew responsible?

A week of suspicions and cover-ups unfolds as Casey and her remaining friends try to stay alive long enough to solve murder mysteries past and present. If they do, their friendship may not survive. If they don't, the house will claim more victims.
