Herbert's Wormhole is a sci-fi comedy with adventure. The beginning starts with a kid named Alex who is into slaying aliens in video games. His parents secretly set up a play date with his neighbor, Herbert. Herbert is an extreme inventor who made silver high-tech suits. These suits lead them into a wormhole into the future. I would recommend this book for ages 6 - up. It is a light read with lots of adventure. J.C. Zimmerman, Grade 6
