I thoroughly enjoyed this book. It was probably the best book I ever read, and I have read a lot of terrific books. Dreamcatcher kept me guessing and exited throughout the entire book, and there were no boring parts. This book is filled with lots of action and tons of crazy events. The basic plot of the book is this: Four friends, Jonsey, Henry, Pete, and The Beav, save an innocent retarded boy from older bullies back when they were kids. They grew close to the boy, who called himself Dudditz, and were linked to each other in a strange way. They could hear each others thoughts and dreams. Each year, the original four friends go hunting up in the Jefferson Track in Maine. But this year their trip wasn't going to be fun. Aliens land there and bring with them an infectious red-colored birus that spreads quickly among people and animals. When the infection reaches a person's intestines, it grows a living, snakelike, beast that rips its way out of your body. The military comes and quarentines the area, holds the infected people in captivity, and slaughters the aliens and infected animals. They killed all the aliens except for one. This one alien, Mr. Grey, happened to find Jonsey and took over his body and had access to his brain. He plans to infect a dog so that is grows a snakelike thing, or birum, in it's stomach and then dump the dog into the area's main water source. This would eventually contaminate every human being on the earth and kill off all mankind. It's up to Henry, Dudditz, and Jonsey to save the world. Can they do it?
