I've just managed to finish The Well of Lost Plots by Jasper Fforde. Perhaps I should have started with the first in the series, because it took me a while to warm to the characters. Anyway, my overwhelming impression of this book is that it's very, very clever.
Fforde has incorporated tons of humorous literary references into this imaginative story of Thursday Next, literary detective, and her adventures in Book World. I can imagine that readers who are already familiar with the works of Austen, Dickens, D.H. Lawrence and so on would find it a huge chuckle. I got a chuckle here and there, but I'm certain that I missed a large number of in-jokes. My saving grace was perhaps knowing enough about computers to enjoy the software upgrade references to Book World's upcoming Book Operationg System. Despite my handicap though, I enjoyed it enough to finish the book and check out the previous one, Lost in a Good Book.
