Can you name a celebrated novelist who you find impossible to read?

Tolkien, in some ways. I know it's contradicting when I say that I love his works but it took me forever and a day to get through Children of Hurin - maybe it's because most of it was put together, actually typed up and edited by his son, so different styles of writing. In that case, it's Christopher Tolkien's work that I can't get through easily. Got through the novel though. Brilliant work.
