A fallen star. A forbidden magic. A betrayal that will shatter a continent.
Commander Kael has lived his entire life by the rigid laws of the light. But when a disastrous ambush strips him of his men and his honour, his only path to redemption lies in retrieving a fallen celestial shard from the lawless borderlands.
Lyra is a rogue who survives in the shadows. Wielding forbidden shadow magic, she thrives outside the oppressive reach of the ruling Courts. Her prize is the exact same volatile meteorite, and she has no intention of surrendering it to a self-righteous soldier.
When a star-mutated abomination traps them both, light and shadow must forge an impossible truce. Surviving the crater requires breaking the most sacred laws of their world by combining their opposing magics.
However, the beast is only the beginning. After discovering a treacherous conspiracy orchestrated by his own superiors, Kael must choose between the Court he has always served and the rogue who is rapidly stripping away his defences. Hunted by elite assassins and carrying a celestial weapon, they must descend into the criminal underworld to neutralise the erratic energy before the Sun King can achieve a godlike ascension.
Can two sworn enemies fuse their broken souls to save Aethelgard, or will the collision of light and dark consume them both?
