Recommend me some long and cluttered fiction

[statij]

LOVE this thread! So many of my favorite books have already been mentioned. One which hasn't, and which fits the criteria very well I think, is The Sot-Weed Factor by John Barth. Long, convoluted, hilarious, brilliant historical fiction.

The Satanic Verses by Salman Rushie.

The Effect of Living Backwards by Heidi Julavits. A plane gets hijacked, but instead of physically threatening the passengers, the captors decide to play psychological games with the passengers. Every other chapter in the book is a story from one of the characters' childhood, providing insight into the reasons they behave the way they do.

Well, I came in to mention House of Leaves and Foucault's Pendulum, but both have already been cited. So, I'll offer Gravity's Rainbow by Pynchon, the virtual definition of long and cluttered.
