Nightwing, Martin Cruz Smith

When an unhappy, aging shaman invokes the Hopi god of death in an effort to bring the world to an end, those around him are sceptical. Then they discover his body, mutilated and bloody, and other similarly disfigured bodies begin to appear. Horses, sheep, cattle - no living thing is safe. But the cause of these horrifying deaths remains unclear…
Enter a young Duran, called back to the reservation to investigate. Duran immediately recognises the significance of the shaman's spell and, with the help of two scientists, he works to combat the supernatural scourge - before there's nothing left to save.
