This book is unique to some other books because Jack and Annie go on vacation without their mom and dad. I think this book is very adventurous and I like it because Jack and Annie have to go places and risk their lives getting books to save a library. My favorite part of the book is when they enter the bookroom and start to read the scrolls and the scrolls are written in Latin so they don't know what they are reading.
I recommend this book to people who like adventurous stories because this book has characters that travel through time and space. There is a lot of action as Jack and Annie race time to get a book called Vir Fortissimus in Mundo before a volcano erupts and almost kills them. I would never want to go on this kind of adventure because it's a very dangerous risk for a nine year old kid like me. Jack and I have nothing in common because Jack goes on many adventures and I go on no adventures. Jack has a sister and I have a brother. Jack lives in Pennsylvania and I live in NJ. I loved this book a lot!
