Summary
"You might think that when you sleep the world sleeps with you, but all through the night others are busy. Firefighters wait for the bell to ring, nurses and doctors look after their patients, postal workers sort letters and parcels. Mums and dads are up feeding their babies, and out in the wild, owls, bats and foxes search for food" -- Back cover.
