Shade of Wings

Four-year-old Duncan needs to hurry up and find a mate - at least, according to his sister, Cloud. But she doesn't know about the mistake that's preventing him from leaving their family to start another.   Though he's the eldest, Duncan doesn't see himself as a father. Yet that's what he must become when both his parents die of the mysterious illness that's killing crows across New York City. He devotes himself to caring for his siblings, including three fledglings - but he soon discovers he can't protect them from the 'blind death.' Meanwhile, a zoo pathologist's worst fears are realized. It starts with dead flamingos. Then critically ill New Yorkers start showing up in hospital emergency rooms. Some blame the crows.
