What I like about Dan Simmons is that no matter what genre he's writing in (and the man's prolific- science fiction, historical fiction, mystery, horror) he always expresses a clear and heart-felt interest in academic subjects, particularly English literature- Chaucer, Edgar Allen Poe, Frank Lloyd Wright, Beowulf, John Keats, and now in his latest book: Charles Dickens and Wilkie Collins.
He writes these little critical essays and weaves them into the narrative of his stories. They're like chapters plucked from somebody's PhD dissertations. Maybe they're the ones he never got a chance to write in grad school. And the research the man does for his work is amazing. I could imagine him employeeing a team of librarians to work on this stuff. And I'm glad for wikipedia, a lot of this material is so obscure, unbelievable, and just plain fun that I never would have thought it actually happened.

This is a horror novel narrated by Wilkie Collins and it concerns a mysterious boogeyman who troubles Charles Dickens in the last years of his life. There have only been a few edge-of-your-seat scary bits so far, seperated by long, meandering pieces of the type I've described above, particularly interesting is a glowing review of Dickens' "Our Mutual Friend" by Dan Simmons nee Wilkie Collins. More impatient readers might consider that fluff or filler, I enjoy it like a long river punctuated by a series of rapids.
Simmons is one of those writers that started off his career very good and gets better the more he writes. If he can keep up this pace, I'd expect people to still talk about him in 150 years too.
