Weekend
Christopher Pike
Paperback
(Scholastic Book Services, March 15, 1986)
"The dream became a nightmare. ...nothing was going the way they'd planned. There was the girl upstairs who was fighting for her life. The phone lines that went dead. And the explosion in the garage that could have killed them all. But not even that prepared them for what happened next. Because while they were getting some sun, someone else was getting revenge-and the terror wouldn't stop until the weekend was over." Taken from back of book.
