by Zilpha Keatley Snyder, originally published in 1966.
Twelve-year-old Harry Houdini Marco is awkward and clumsy. But when he returns a suitcase lost by a funny little man he met on the bus, he is rewarded with the gift of flight. Two drops of a magic potion rubbed on his shoulders is all it takes for Harry to sprout wings and soar high above the his house, the city, and the California coastline.
