Luna loves living on the moon. She enjoys helping her father – a Moon Miner – on his search for precious minerals and rocks. But when a devastating meteor strike destroys their base, Luna is left stranded alone on the moon. With no shelter and few supplies, she must find a way to survive. The problem is – any hope of rescue is at least 3 days and 400,000 kilometres away … and her oxygen is fast running out!
