Seiko is thriving in the life he has painstakingly built far from the possessive, if not obsessive, loves of Hiro and Zuko. It is a life he fought hard to create, one that feels safe and wholly his own. But the world he left behind has never let him go. The ties he believed broken remain unyielding, and now they are dragging him back—against his will. His fragile peace is shattered as the shadows of his past, composed of gods and immortals, collide with his present, composed of mortals and ordinary humans. Now, the present is on the brink of destruction. The immortals want to annihilate the mortal world so they can start over. And Seiko has to protect the people he loves, including his mates, Zuko and Hiro, who seem to be on the side of the immortals.
