If you're more interested in dialogue than description, you need to grab up a Jack Vance book -- his dialogue is unmatched by anyone else I've ever read. I'd suggest his "Dying Earth" series: The Dying Earth (a series of short stories), The Eyes of the Overworld (a novel), Cugel's Saga (a sequel novel), and Rhialto the Marvelous (a series of much longer short stories). Other than probably wanting to read book two before book three, you can read them in any order. They take place on an Earth millions of years in the future, where magic has been rediscovered and the general consensus is that the sun could die out any day now. The Dying Earth series also has the distinction of being the source of the "fire and forget" magic system from D&D -- also known as "Vancian magic" for obvious reasons. Likewise, you can see the original source of IOUN stones in the last book.
