If you haven't read Jasper Fforde's satirical bibliophile series, go out immediately and pick up The Eyre Affair (read my take on it here). Yes, you have to read the series in order, and yes it can be a tad confusing if you don't keep up, but it's funny, mind-bending, and well...deep.
See, there's this BookWorld where characters from every book ever written live. Books that haven't been read in a while still populate the world, with their characters vying for attention in back alleys of the footnoterphone conduits. There's also time travel, cheese smuggling from The Welsh Republic, and an evil corporation bent on taking over both the real world and BookWorld.
Famous characters police the book world making sure that metaphors aren't sold from one piece of fiction to another. There's always a black market, especially since this world is based on fictional books, which are often based on the real world or the Outland.
I enjoyed this book, not as much as the first 4 (Eyre Affair, Lost in a Good Book, The Well of Lost Plots, and Something Rotten) but so so much more than the last one (First Among Sequels). I even enjoyed the audios, though haven't listened to Missing...grabbed it as soon as the library received it.
Recommended for those who enjoy alternite history, humor, satire, books, Shakespeare, books, history, and yes...books.
