After a week of reading three pages of Heart-Shaped Box and then not being able to go on out of fear, I took the plunge this morning and read the thing all the way through.
I'm glad I did. It's Joe Hill's first novel and he certainly seems to have picked up some of his fathers (Stephen King, you know, that guy I think is one of the greatest writers alive) genius.
The story is quite well paced, terrifying and moving. And the ending is my kind of ending!! Highly recommended.
