Paris, turn of the century.

In a city ruined by a magical war, the magical factions known as Houses intrigue against each other to gain power.

House Harrier is no one's friend, which leaves an ample trail of suspects when a mysterious magical explosion devastates the House and its surrrounding areas. Emmanuelle, partner of the head of House Silverspires, finds herself in the ruins of House Harrier with no memories of the explosion, struggling to navigate amnesia and survive in hostile territory. Thuan, co-head of House Hawthorn, navigates his prickly relationship to his husband while dealing with changed politics and dark magic. And Philippe, once an immortal, accompanies an envoy from his own country in the East, seeking a missing spirit with great power.

But the flames are rising, and vengeance is coming for those who fought in the war, and their descendants. They will have to stand together, or burn alone...
