its a good book with twists and turns and it will keep you interested and intreated to this book. my family has been on PJ library for over the 8 years and this HAS to be one of the best. If you like books with suspense, surprises, cliffhangers, and a story that will touch your heart, READ THIS BOOK!

I would have liked it if there was more action, but it was fine.

You should definitely get this book. It is a great book. It's about David digging a time tunnel. It was fun to read.

It was good.
