The Well of Lost Plots By Jasper Fforde

Thursday Next is a real person in this book. She is from Swindon, England. She has a family; her mother, her father who technically doesn't exist, and two brothers, one of whom died fighting in the Crimean war. She has a pet dodo named Pickwick. Her husband was eradicated by the Chrono-Guard. She has saved the world from one member of the Hades family, notorious and deadly killers. She works for the Special Operations Literary Technicians, but moon-lights at Juris-fiction. And she is living inside a book in the Well of Lost Plots, the 26 floors of Sub-Basements to the Great Library that house all of the books and written works that have never been published. She works around books who are trying to get published by improving plots and storylines and applying to the Council of Genres. The misconception is that authors write books. The truth is there are thousands of people living inside the book who construct the story themselves. And there is somebody trying to mess with the rhythm of the book world and Thursday is determined with putting a stop to it. At the same time, there are people trying to implement a new way to read that doesn't actually work, but they are trying to sell it anyways, and Aornis Hades has demanded revenge for the death of her brother Acheron and has planted a mind-worm in Thursday's head that has been eating away at her memories. Trying to hold on to her memories and her job in Juris-fiction and her life at the same time, Thursday has to save the entire world from a miserable book-less existence.
I would most definitely recommend this whole series to anybody who likes reading witty and poignant fictional books about books and mysteries and crazy alternate histories, but you would have to read all of the other books first or else you really wouldn't understand anything that was going on, especially with all of the continuous plot twists that keep happening. This book should be good for anybody 13 and up because of some crude humor and stuff like that but its really really great and everybody should read it because its awesome!!!
