This is a Stephen King book in which a dude is bequeathed a doorway back into time. Hilarity follows.
It has been a pretty long time since I read any King.... I kinda forgot what a bummer he can be, at times. Parts of it reminded me of The Talisman. Parts reminded me of The Dark Tower. Parts of it reminded me of IT. There were crossovers with his other books, as is his wont.
Anyway, this is a page turner. I read the 900ish pages in about 4 days. If you like Stephen King, this is more Stephen King so you might like it.
