'On a starry night, if I look at the sky I feel small, as though I were a grain of sand compared to a planet.' In this big world there are times when we can feel very small. The moon is small compared to the Earth; the Earth is small compared to the sun; likewise the sun, compared to other stars. But, really, what are we? Big or small? This book explores an emotional microuniverse and reminds us that some things, however small they seem, are capable of changing reality - the reader's reality or indeed the reality of all of us.
