In a world where the sun is slowly dying, humanity survives under the faint glow of Aether Crystals. The dwindling crystals provide light and mining of Aether Crystals is the most important job. Eira (Sunny) Solwyn, an eighteen year old girl from the slums of Eclipsia discovers she is the Last Spark- the prophesied one rumoured to ignite the sun and save the world.
Her power comes at a grave cost and her life is in serious danger as a ruthless organisation known as the Shade Collective seek to harness her powers for their own dark purposes.
