The boy on the porch
(Book)

"One day a young couple wakes to find a boy asleep on their porch. Unable to speak, the boy cannot explain his history. What kind of people would leave their child with strangers? All John and Marta know is that they have been chosen to care for this boy. As their connection to him grows, they embrace his exuberant spirit and talents. The three of them blossom into an unlikely family, but how long can their happiness last?"-- From dust jacket flap.
