I love Stephen King. Not in a I'm-going-to-stalk-him -kinda way, but in a he's-given-me-so-much-I-love-him-for-it -kinda way.
Granted, not all his novels are masterpieces but he is a great storyteller. There are few writers who can capture the feel of bonding and friendship better than him (the children in IT, Stand by Me, The Dark Tower -series for example).
The latest I've read from him is The Cell (Lisey's Story isn't published here yet) and the man still has it.
If I'm forced to pick a favourite, it's the whole Dark Tower series. I love each and every main character, from Roland to Oy. The talent King has, IMO, is that he creates amazing characters. Yes, he's good at storytelling and his plots are great. But it's the characters that stick to my mind and stay with me.
