Why are the night skies quiet? Might we be alone in the Cosmos? 'Alone' helps to shed some light on the mystery of the Great Silence by exploring such topics as Fermi's Paradox, The Great Filter and the Kardashev scale. Ultimately it shows why it may be our duty to both explore the Universe and take care of each other. Presented as an illustrated children's book, it aims to provide inspiration for inquisitive, eager and reflective minds... both young and old.
