Summary:
The alliance rune means everything to Magnus. When Alec works the night patrol and Magnus is left alone in their bed, a sudden pulse of elation soothes his wracked soul. Sharing his magic with Alec, who has such a childlike whimsy for sorcery, feels more intimate than any time they spend between silk sheets. Knowing Alexander is safe and always with him — it’s more than Magnus could have ever dreamed of. A bond, something tangible keeping them tethered so they can always find their way back to each other.
When a mission goes awry, and Alec almost perishes at the hands of a unique demon, the others start to notice something’s off about him. He heals too fast, his skin’s devoid of any wrinkles, and he still has the body of a twenty year old. He seemingly hasn’t aged a bit, and neither has Clary. While the gang investigates how to banish the demon back to Edom, they learn more about the alliance rune than they ever thought possible.
