Silver Blood

Becca and the other dragons are hot on the trail of the Chorus of Demiurge. Committed to defeating them, they turn their sights upon tracking the dragons kidnapped and corrupted by their enemies.
When they finally locate one, though, they are shocked to discover that it comes with an offer from Tamiel: if they remove themselves from the conflict, they will be spared the coming apocalypse.
To make matters worse, they learn that the kidnapped dragons are so corrupted, Becca can't even begin to undo the damage without risking killing them.
With the corrupted dragons a lynchpin in Tamiel's plan, Becca turns her sights towards the only thing she can do: she has to find a way to cure them, or the world as they know it is doomed.
