The Lost Children, Josephine is wondering about her father's shed, when a boy she's never seen walks up to her. He disappears later, and Josephine wants to find out where he went. She thought he was in the shed, but when she goes in there and presses the back wall, something happens. She finds herself in an alternate dimension, full of monsters and the Master. In this tale of wormholes and traveling to other dimensions, you will experience Josephine's adventure as if it's your own.
I was enjoying this book until they explained the concept of wormholes. It just took away the magic. This book was good, though. I think that the idea was really good and that anyone should read this book.
