A group of friends from Carlson High School receive a mysterious chain letter that moves from their email accounts and text messaging to a creepy little icon that begins haunting their My Space pages. Who knew they should take the threats of these messages seriously? Or that chain letters can kill? As the friends battle the curse or a perpetrator targeting them-how can they know for sure? Friendships are tested. The ominous message begins killing them in the most gruesome ways imaginable, turning friend against friend with ''rules'' that seem impossible to escape. The chain letter must be passed to the people they know best. That person must open the letter. Break the chain and a horrible death awaits you. Beat it and you just might live. Do you pass it on? Does friendship mean anything? Can Jessie and her remaining friends outsmart the vengeful Chain man before he gets them?
