Query: Christopher Pike-The Wishing Stone

This book is a very good book for young readers. It is about 4 kids that find a stone while walking in a wood one day and whenever they ask for someting with the stone in their hand, it immediately appears in front of them. But there is a catch, they must pay off their wishes by slaving away on a planet far away. The two girls are taken away but the boys manage to survive and go on a long and tiring misson to go and save the girls from the slave planet.I would rate this book four stars as it is a good read and keeps the suspense up.
