Book excerpt: Heaven is rays of sunlight dancing slowly on wheat stalks. It's wind twirling itself around chimes hung from low tree branches, and robust bursts of scent and color, far beyond anything describable with words.Heaven is a flightless crow, a promise of forever tied to a necklace, and hidden love letters tucked away safely inside a tree.Heaven is a fire-haired boy named Rust and his love for Ancel, a boy full of storm clouds.Heaven is all the tiny threads of hope that hold them together.
