Good morning Mark Hamilton, I finally finish reading the superpuzzle. Some of the journeys were sad especially when Sally and Jasmine lost the parents. But I really got excited at the end. Throughout the book I felt as if I was walking that journey with them I was evening laughing at the end like the people on the streets. I wanted to know if there is really a eighteen year old serum on the market yet if so I would like to have one. Shannon W.
