Next in the Thursday Next series. This takes place 14 years after the last book. Her kids are teenagers. She thinks that she has 3 kids (but she only has 2. Aornis gave her a mind worm as a cruel joke that makes her think she has a 3rd kid) Her family humors her!
This book is all about making sure that time travel is invented so that the people that have been time traveling for 50 years can continue and the time continium (sp) will not roll up and end the world. Very funny & witty as all these books are.
