The setting is Nazi Germany during Hitler's reign,
A young woman working at an orphanage is cringing in fear for her life during a raid by the Gestapo's SS soldiers when one of the soldiers secretly sets her and a little girl free. They will have to make their way through miles of dense forest without food or water.
Some miles away a boy is brought into the Joachim Insane Asylum for help. He had been camping in the forest with two friends when something happened that left him helplessly catatonic and the other two boys missing.
What evil mysteries hide in the forest ?? The town people are terrified and there is talk of wolves and witches. What is the Contraption?? You will want to stay up all night and read this book. But it is better to take your time and savor every moment of this exciting roller coaster ride. I actually read it twice and I think I enjoyed it even more the second time around.
