Newbery Medalist Tae Keller continues the fantasy adventures of Mihi Whan Park and her friends as they revisit the fairy tale realm to solve a giant problem.

After just barely surviving their last trip to the Rainbow Realm, Mihi Whan Park and her friends Reese and Savannah know that stepping back through the library refrigerator and into the magical fairy-tale world would be a dangerous choice. But when they discover that Mihi’s nemesis, Genevieve, has crossed through the fridge and into the Rainbow Realm herself, Mihi, Reese, and Savannah decide they must bring her home.

Through the refrigerator they go, and when they arrive, they find the world has changed. Atop an enormous beanstalk, a greedy giant wreaks havoc on the realm, and Genevieve isn’t the only one who needs saving. Now Mihi and her friends must team up with villains, concoct a magical disguise, and infiltrate a party full of the most fearsome creatures in all the land. What could possibly go wrong?
