📖 Summary
Lois Duncan crafts a riveting tale of suspense and psychological dread in I Know What You Did Last Summer, a classic work of juvenile fiction that explores the harrowing consequences of a single catastrophic mistake. The narrative centers on four teenagers who find their lives forever altered following a tragic accident. Stricken with panic and facing a future they believe is ruined, the group makes a desperate, binding pact to conceal a shocking secret, burying the truth along with the immediate aftermath of the event, hoping to simply move on and pretend it never happened. However, the past proves to be an unforgiving master. As time marches forward, the illusion of safety shatters when someone learns the chilling truth of what transpired during those fateful months. A relentless campaign of psychological torment begins, thrusting the terrified friends back into a waking nightmare.
