From the shoulders slowly a pair of wings unfolded, wings made of rainbows, of light upon water, of poetry.
With a gesture both delicate and strong Mrs. Whatsit knelt in front of the children, stretching her wings wide and holding them steady, but quivering. "Onto my back, now," the new voice said.
The children took hesitant steps toward the beautiful creature.
