Reading Level: Ages 9 - 12
Eleven-year-old twins, Nick and Tesla, are sent to spend the summer with their comical, mad scientist uncle while their parents are out of the country. Instead of the boring time they expect, they encounter a spooky deserted mansion guarded by ravenous dogs, a mysterious girl at the window holding a "GO AWAY" sign, ill-tempered construction workers, and black van that keeps following them. The twins are science geeks themselves who use everyday objects to build what they need to solve the mystery and survive. Interspersed in the book are great directions for building the gadgets. Have fun!
