Best Answer - Chosen by Asker: If you liked Heroes on TV go for Firestarter.
The Regulators was the only book to cause me to lose sleep.
Dark Tower is very long, but good. Better after you've read some other books first.
Nightmares and Dreamscapes is good collection.
Eye of the Dragon is also good.
