What if everything you thought you knew about the universe was a lie? Fourteen year old Mia McAdams’ world is turned upside down when she finds herself torn from her life on Earth and transplanted onto the planet Usonia – a secret utopic world colonised after the second world war to safeguard the human race. Submerged into this new reality, Mia quickly falls in love with the glittering planet and its alluring, other-worldly inhabitants. But when the future of Usonia comes under threat, it soon becomes clear that Mia holds the key to its survival.

Can a team of teenagers from another planet help change the world? Six months after fifteen year old Mia McAdams lands on the secret planet Usonia, a shipment of Earth’s most brilliant individuals descends on the colony. Tasked with speeding up progress on the utopic planet, the determined and ambitious new arrivals aren’t afraid to ruffle a few Usonian feathers. Meanwhile, Mia is preparing to say goodbye to her idyllic new life on Usonia, leaving her boyfriend and first love, Noah behind. Joined by her best friend Stella, her devilishly charming new teammate Kale, and a host of Usonians, Mia is set to fly to Earth on a mission to change the world. But will they succeed? Operation Earth is the second book in the teen sci-fi trilogy, Project Ark.

Planet Earth has been wiped out after the most final war in history. The last remaining survivors have made it to the planet Usonia - a secret colony built after the second world war to protect the human race in the event of nuclear warfare. A utopian world that puts equality, freedom, peace and the planet above all. A glittering world devoid of pollution, banks, governments and police. The final shipment from Earth is scheduled to descend on the planet. The planet’s resources are already stretched to the limits and the Usonians have been working all hours to prepare for the mass arrival of asylum-seekers from all around the world. Scared, malnourished and traumatised, the Earthlings must adapt to a new life. Integrating with alien inhabitants on a planet that they had no idea existed until now. A planet where there are no fast food chains, no super markets, and no laws. As the population grows, the planet’s idyllic way of living quickly begins to deteriorate. Crime, discord and tragedy are all new to the peaceful planet, and the inhabitants must act fast to prevent the planet becoming another Earth. In the final instalment of the Project Ark trilogy, sixteen year old Earthling, Mia McAdams and her friends from all over the universe must work together to save the human race. One last time.
