I would recommend you read Insomnia next, that is my personal favorite. It’s also definitely on the longer side, but so are the other books you read. If you want something shorter I would go with The Green Mile, or Tommyknockers. 

I dont care how long they are, i just love his books and i will definitely read that one. Thank you

Welcome.

Stephen king just released later that could be and it will show how he progressed as a writer when he was in his 20s

I'm in the midst of the dark tower series now

Just started reading dark tower a few hours ago
