I didn't really like this book because it left you with a cliff hanger and I am not very interested in reading more of this series. I did like that it was an adventure. I would recommend this book to people who like to read a whole series.

I would like these books because they look mysterious and adventurous and I like that kind of thing.

I'd like this book because it looks a little bit exciting and surprising. I also want this book because there is code breaking and a lot of adventure.

This book was very fun because it was full of mystery and the characters liked to do some things that I do...like figure out puzzles and be active. I also liked the book because there was a little bit of danger but it all turned out good.

I liked this book because it almost felt like it started in real life but then it went into fiction. The characters were very likable and active. The story line is easy to follow. It was a little bit repetitive and that wasn't my favorite.

I like this book because it's humans in a different world. It also has a lot of heart and family and friends who always help each other. It's also fun because it's a little bit of a mystery but in the end it all makes sense.

I liked that this book was actually based on Zach King's life but still fiction. I also like it because it's magical and I like that type of book.

I really like this book because the characters have adventures and the best part is that they are family. It's also fun because they are running away from a mean old baker lady and her husband who want to send their brother to an orphanage.

I really like this book because it was a little bit creepy and full of mystery. Seth and Kendra are very likeable and their Grandpa's house sounds very interesting to live in. And, if I was in Kendra's shoes I would discover something new every day.

Wow! This is a really good book and Mr. Grabenstein did a really good job. It's fun because you can figure out some of the riddles and puzzles on your own. I also like it because the characters are very involved and very likeable- except one. And if you read this book you will find out who (and trust me, you will not like him).
