Sixteen-year-old Diana is a genius. She has, for the past two years, endured a habitat with gravity six times that of her comfortable, familiar life in Luna. All so that she can go to school on Earth where her heroes, Albert Einstein and Marie Curie had worked and studied. That is until she and her family are forced to flee the moon – in a kilometre long solar sailing tree named Minerva.
As Diana and her family voyage to the outer reaches of the solar system, she must learn to cope with the loss of her friends, missed opportunities and dealing with the societies in the Asteroid Belt and to the outer reaches of Saturn. In this coming-of-age tale, Diana learns that there is a wider world out there beyond the Lunar warrens and that she has a role to play in it.
