Who hasn't longed to jump inside a book and see the events play out?
Okay, maybe some people.
But for those who have, Thursday Next by Jasper Fforde is an excellent series to read. It takes place in a world where Baconists go door-to-door prostlytzing, the Crimean War is in its 158th year, and pet dodos are all the rage. The best part, however, comes after the first book, when Thursday becomes a member of Jurisfiction, an organization that makes sure books stay as they are written by keeping an eye on the characters from the inside. Tons of side jokes that writes will enjoy, and a fairly clean read.
