Wishmoley and the Little Piece of Sky by Julia Hubery
Most moles like to stay underground, dig-dig-digging. But not Wishmoley. He spends his time dreaming about the world above. One day, when Wishmoley finally tunnels up to the surface, he discovers the big, beautiful sky and decides he loves it so much that he would like his own little piece of it. It is a heart-warming book about love and letting go.
