It is a 1986 horror novel by American author Stephen King. It was his 22nd book and his 17th novel written under his own name. The story follows the experiences of seven children as they are terrorized by an evil entity that exploits the fears of its victims to disguise itself while hunting its prey.
They were seven teenagers when they first stumbled upon the horror. Now they are grown-up men and women who have gone out into the big world to gain success and happiness. But the promise they made twenty-eight years ago calls them reunite in the same place where, as teenagers, they battled an evil creature that preyed on the city’s children. Now, children are being murdered again and their repressed memories of that terrifying summer return as they prepare to once again battle the monster lurking in Derry’s sewers.
Readers of Stephen King know that Derry, Maine, is a place with a deep, dark hold on the author. It reappears in many of his books, including Bag of Bones, Hearts in Atlantis, and 11/22/63. But it all starts with It.
