What does it take to build your very own planet? Orson is about to find out. He takes: A cup full of rocks A dash of water A sprinkling of metal A lot of nothingness A big bang ... And before long, BOOM! He has it – a tiny planet with rings around it, right there in his bedroom! But it seems that BUILDING a planet is the easy bit; taking care of it is a different thing altogether. Over time, Orson realises that his planet needs to be free and that sometimes you have to let go of the things that you love the most ... A heart-warming story about life's possibilities and disappointments with an uplifting ending that will resonate with all fans of Oliver Jeffers' work.
