Fleur Du Mal
Happened to me with Watchmen as well. I queued for it almost a month. When I finally had it in my hands, on one Friday night last Fall, I thought that reading it was going to take some time, yet I had finished it already on Sunday.
Exciting plot, highly intellectual content, several layers, deconstruction of superheros, all made for gluing the book in my hands.
Fantasy-Genre: Ursula LeGuin's Earthsea series. Six books, each read in one sitting, first 4 books I've read twice that way. They have exceptionally strong themes, I love the humanity and freedom of imagination. The second book, The Tombs of Atuan, is perhaps the most enticing as large parts of it took place in total darkness, and it had elements of horror, which appeals to me.
Thematically, The Hickman-Weis DragonLance Twins-trilogy is maybe weaker, but very easy to get into. I read the three books in two days. That is, for the second time, when I finally got them purchased to my own personal library. =P It was slower when I had to use the library for I couldn't get them all out the same time. =P
3) Pretty much anything Arturo Perez-Reverte has written and I've gotten my hands on so far. El Capitan Alatriste (not sure if its title is in English Captain Alatriste or something more imaginative) would be an example of those books that have that 'page-turning' quality, as Firefly puts it, ---it's a fast-paced adventure tale, but not really that deep. El pintor del batallas -- Painter of Battles? is a really dramatic tale of the mind of a war photographer, strongly thematic, not pathetic at all.
I would love to elaborate my latest literary experience with a novel of his, especially since I laid my hands on it right after oDrew had made a thread about indirect narration in the Lit.Dis and I was able to take note on different aspects of that, plus there's the pretty skillful use of two different narrative voices, but the book really has content-wise absolutely nothing to do with PG-13, so I'm frankly hesitant/afraid to even name it here.
There have been other books that I couldn't put away and read while I was walking from place A to place B, but these came up to my mind first.
