Hi . My favourite of his is 'The Stand'.
I also particularly like: Rose Madder, The Green Mile, Desperation, Needful Things, The Talisman, Misery and the Gunslinger/Dark Tower series. If you try the first book of this series, The Gunslinger, and if you like it, you will have several other volumes that follow to keep you occupied!
(I didn't much like Pet Semetary.)
