When her little brother Gip touches the magic portal in the cave (which she *told* him was a very bad idea) and gets sucked into another world, 12.67-year-old Soryn has no choice but to dive in after him. On the other side, Gip isn't the only one who needs rescuing. The Hub that connects all the portals is in peril, and Soryn's Science might be the only hope for solving the puzzle. With the "help" of an annoying girl and her flying cat, Soryn finds out that saving the day with Science is the easy part. Friendships... are a lot more complicated.
