In the series opener, Jack and the Geniuses: At The Bottom of The World, readers meet Jack and his foster siblings, Ava and Matt, who are orphans. But they’re not your typical kind of orphans—they’re geniuses. Well, Ava and Matt are, which sometimes makes life difficult for twelve-year-old Jack. Ava speaks multiple languages and builds robots for fun, and Matt is into astronomy and a whiz at math. As for Jack, it’s hard to stand out when he’s surrounded by geniuses all the time.

When the kids try to spy on Dr. Hank Witherspoon, one of the world’s leading scientists, they end up working for him in his incredible laboratory. Soon, Hank and the kids travel to Antarctica for a prestigious science competition, but they find that all is not as it seems: A fellow scientist has gone missing, and so has any trace of her research. Could someone be trying to use her findings to win the contest? It’s up to Jack, Ava, and Matt to find the missing scientist and discover who’s behind it all—before it’s too late.
