Herbert's Wormhole
3 primary works
Book 1
When almost-sixth-grader Alex, a video game fanatic, is forced on a "playdate" with his neighbor Herbert, an inventor, the two travel to the twenty-second century and face off against aliens, who are not as beneficent as most people think.
Book 2
Pretending to be alien slayers when they travel via a wormhole to their hometown 100 years in the future, eleven-year-olds Alex, Herbert, and Sammi must pull together when an actual alien invasion occurs.
Book 3
"Herbert, Alex, and Sammie are pretty sure their adventures in the future are over until they meet their greatest villain yet: Sammie's future self, AeroStar, a power-mad tyrant who wants revenge. It's up to our heroes to once again don the mantle of the AlienSlayers and somehow try to save the past, present, and the future from total annihilation"--
