Hummingbears, a red wish tree, and a gorilla who lives in a shopping mall. You'll find all of these fantastical images and more in the children's books of Katherine Applegate. Applegate is a New York Times best-selling author. Her book "The One and Only Ivan" won a Newbery Medal. Applegate is now out with a new book called Willodeen. It's the story of an 11-year-old girl who loves animals and wants to care for the earth. On this week's Cityscape, Applegate shares how she aims to inspire kids to foster a love of reading and a curiosity about the world around them.
