Zolushka, whose name means Cinderella, is a Siberian tigress from Russia, who was rescued by hunters, rehabilitated and successfully released back into the wild. There, she finds her Prince Charming and has two cubs. Fifth graders at the P.S. 107 John W. Kimball Learning Center, an elementary school in Park Slope, Brooklyn, wrote and illustrated this real-life fairy tale and conservation success story, the fourth book in a series about endangered animals. The year-long project was a collaboration between P.S. 107's Beast Relief committee and the Wildlife Conservation Society. All proceeds from sale of the book will go directly to the conservation of Siberian tigers in the wild.
