(pb; 1973, 1978, 2010: YA horror novel)
From the back cover:
"They didn't mean it. They didn't mean to hit the boy. There was a party, and it was an accident. . . but they had futures to protect. So Barry, Julie, Helen, and Ray swore one another to secrecy. But now, a year later, someone knows. Julie receives a haunting, anonymous threat: 'I know what you did last summer.'
"The dark lie is unearthed, and before the four friends know it, they need to outsmart a killer. . . or they will be the next to die."
Above-average, suspenseful-for-young-adults read that, while it sports a few uses of (situation suitable) profanity ("sh*t") and casual references to smoking pot, resonates in a real-world and teen-friendly way.
Worth owning, this.
The more violent, loosely-based-on-the-book film was released stateside on October 17, 1997.
