A flock of birds was moving toward me along the river, hovering over something floating on the water. It drifted downstream, closer and closer, until finally it bumped up against the dock. Though it was covered with leaves and branches, now I could tell that it was a raft. I reached down and pushed some of the leaves aside. Beneath them was a drawing of a rabbit. It looked like those ancient cave paintings I'd seen in books — just outlines, but wild and fast and free. Nicky isn't one bit happy about spending the summer with his grandma in the Wisconsin woods, but them the raft appears and changes everything. As Nicky explores, the raft works a subtle magic, opening up the wonders all around him — the animals of river and woods, his grandmother's humor and wisdom, and his own special talent as an artist.
