Both of these books are in the "Thursday Next" series. I loved them. In the Well of Lost Plots, Thursday's husband has been eradicated and she needs a place to escape for a while. So she goes to the "well". This is where unpublished books wait to be published or erased. They are mostly poorly written books. So the characters of these books are really funny.
In Something Rotten, Thursday is seriously fighting Yurrick Kaine. He is a fictional character who has escaped into the real world. And he is trying to become dictator of the world with the help of an invention called the ovinator (which when turned on - makes everyone think that what you say makes perfect sense). She also gets called upon the help lead the Swindon Mallets to victory in the Super Hoop. What, you didn't know that croquet is the hottest national sport? Well with the help of a group of reengineered neanderthals, this may just happen. By the way, if the Mellets don't win, there is a good chance that Kaine will become the dictator and the world will soon be in World War 3. No pressure!
Very good series!!!
