My Grandpa is a Mad Scientist

By Robert Zangari

Lexile Level: 570 L Grade Level 3-7

Gabe is on summer break after seventh grade and his mom is making him spend the vacation time with his reclusive grandpa from out west.

Luckily, his cousin Jake will be there. Gabe had only met him once, years ago, but he couldn't remember much of him.

To Gabe's surprise, he wasn't staying in a hovel but a lavish castle, with dozens of guest rooms, a full-sized theater, a private tennis court, and a detached garage with dozens of sports cars.

With plenty of things to do there wasn't time to cause any mischief, that is until Gabe and Jake find out their grandfather has a hidden laboratory with all sorts of bizarre experiments.
