I also prefer heavy dialogue in my reading. Books that are primarily world building an be a struggle. I read a lot, averaging about 40 pages a day, every day, but I also indiscriminately put books down and move on, so it helps to keep me engaged in the habit. I have to maintain a large backlog, though, but it's never been an issue.

edit/ I'm also entertaining the idea of getting into graphic novels and seeing how I respond to them.
