To assist world leaders with the climate crisis, Earth's witches step forwards from the shadows. The result: cleaner oceans, safe forests, and a good amount of the population living in space colonies to prevent overcrowding.

Hundreds of years later, Cosmic Witch - the organisation that pioneered the way - have ordered the removal of environmental balancing units from four young colonies. For Tia, a guilt and grief-stricken witch aboard The Merlin – the ship tasked with the mission – something feels off.

Battling her inner demons and her crush on the captain, Tia and her friends dig deeper into the reasons behind the mission. Soon, they find themselves wrapped up in a conspiracy none dreamt possible.
