the book was really short but it was good. Two kids come into a tunnel and find themselves in another time period. It was awesome!!!!!!!!!!!!!!!!!!!!!!!!!!!!! They learn more about history and stuff. It was cool

I liked the book but I read the whole thing in, like, one hour. Way too short. It's only 96 pages!

I didn't feel very involved or interested in this book. Maybe that's just me, but I didn't really like it.

It was ok. To me it was a little scary.

I would have liked the book to have more action and suspense.
