Not all of London can be seen. Sol has spent his life moving through the city unnoticed, keeping to its edges with the man who raised him. Amicus has always known where to go, when to leave, and what not to explain. He calls it protection. But when a sudden act of violence tears through the fragile life they've built, the rules that kept Sol safe begin to unravel. The city starts to change. Something takes shape where nothing should. Figures move where no one stands. And beneath the London Sol knows, something stranger begins to surface, a hidden world shaped by memory, power, and everything the city has chosen to forget. As that world draws closer, the balance between them begins to shift. Amicus is weakening. Sol is changing. And the truth he has been kept from is no longer something he can outrun. Because some things are not meant to be seen. Until they are.
