Pamela Devereux and Grandson Jason watched the feathered visitors swoop down to the old weathered aviary on the deck of her Southern California mountain home. The aviary door had disappeared long ago, and the birds could come and go freely, attracted by the bowls of fresh water and birdseed that Pamela refilled daily. When a young Rock Pigeon returns to the aviary again after several recent visits, Pamela recalls the strange events that began twenty years earlier: How a visitor to the aviary from another time helped to save her son, the father of Grandson Jason. THE AVIARY is a tale of alternate history and the unintended consequences that follow as countries in conflict race to develop terrible new weapons of war.
