His beloved fairy queen has gone away, leaving him with a very important job: He must protect the forest from a most dangerous enemy—humans.When a determined invader trespasses on his territory, Nix’s skills are put to the test as he invents several wicked tricks to chase the sorry fellow away. But when his efforts don’t go quite according to plan, it becomes clear that this intruder—and this sprite—may not be at all what they seem.

    A cryptic picture message from their mother leads them to a familiar gate in the woods, but comfortable sights quickly give way to a new world entirely—Down—one inhabited by talking birds and the evil Puppeteer queen. Summer and Bird are quickly separated, and their divided hearts lead them each in a very different direction in the quest to find their parents, vanquish the Puppeteer, lead the birds back to their Green Home, and discover the identity of the true bird queen.With breathtaking language and deliciously inventive details, Katherine Catmull has created a world unlike any other, skillfully blurring the lines between magic and reality and bringing to life a completely authentic cast of characters and creatures.
