Definitely 'It'. The story of the Losers' Club and their battle against Pennywise is iconic. The kids' fear, the bond they form, and the horrifying encounters in Derry are unforgettable. It has been adapted into movies and miniseries, which has made it even more well - known.
The Dark Tower series also has connections to Derry. The series is complex and vast, but Derry is part of the greater King universe that the Dark Tower encompasses. It shows how King weaves different stories together, and Derry serves as a key location that ties in with the overarching themes of good and evil, and the journey of the characters.
Derry is a town in Stephen King's works that is haunted by various malevolent forces. It is a place where strange and terrifying events occur frequently. For example, in 'It', Derry is the setting where the shape - shifting monster preys on the children of the town. The town itself seems to have a malevolent will of its own, with its old, decaying buildings and secrets buried in its history.
I don't think so off the top of my head. But Stephen King has written so many novels, it could be a minor character I'm not remembering. Maybe do a detailed search or check some fan forums for a definite answer.
In Stephen King's works, Derry appears in multiple novels as a town with a dark and mysterious history. It plays a significant role in creating a creepy atmosphere for the stories.
I'd say a considerable amount. Maine seems to be a favorite setting for King. Novels like 'The Shining' and 'Cujo' also take place there. It's almost like a trademark of his writing.
