Book excerpt: In this “vividly drawn fantasy” from the Newbery Honoree, the trees of Green-sky are peaceful, while Teera struggles to survive below the forest floor (Publishers Weekly). While the Kindar thrive in the leafy utopia of Green-sky, the Erdlings struggle to survive in their underground caves and tunnels. Hunger threatens, and Teera, an eight-year-old Erdling, is forced to run away before her pet, Haba, is killed for food. Once away, Teera finds her way to the beautiful forest floor, where the sights are breathtaking and the food is abundant. There, she meets the friendly Ol-zhaan Raamo and Neric. Teera and her new Ol-zhaan friends want to reveal the truth about life above and below the trees, but powerful forces are at work to ensure that the two worlds remain apart. This ebook features an extended biography of Zilpha Keatley Snyder.
