The Boy with the Tiger's Heart — Linda Coggin

When Nona's guardian kills himself, she is suspected of murder. In a world where nature and darkness are feared, wild animals are held captive and cities are illuminated by permanent light, who will believe her? Nona must flee with her only friend—a bear who is strangely human. In their attempt to escape capture, they encounter two strange boys, Caius and Jay. Together, the four of them will hide, and fight, and make deadly enemies in their race to a forbidden place called The Edge—where nature is unrestrained, where there is light and shade, forest and mountain, and where there are no shackles or boundaries. A poetic, haunting, and unforgettable modern fable about what it is that makes us human.
