Query: Punny

This is the second book in the Thursday Next series, and is every bit as good as the first. In Lost in a Good Book, Thursday Next must save the world while trying to rescue her eradicated husband Landen. Fforde's writing is humorous, making for a quick, light read. Several reviewers said this book is darker than the first, which I suppose it is, though it never would have occurred to me. It has very little violence and given the nature of Fforde's universe everything is reversible, so what does it matter if the attacks on Thursday are a little more personal in this book? I plan on reading the rest of the series, but I think I'll take a break and clean the puns out of my brain before I start another one. Fforde's humor is great, but I just can't read punny humor continuously.
