This book is great it has twists so you can’t stop reading it (I couldn’t all night) yes I would recommend it though it is a little short

A boy named Dan finds a tunnel in a cave.He asks his friend Sharon to come and explore the tunnel with him.They go down the tunnel and find their self back in time . Dan and Sharon have to find a way to go back up the tunnel and into the future.

It was to short

Really creative idea

this book was so heartwarming!!! I recomend it!!!
