Dark Shadow Darkhaven Saga, Book 6

It's been four weeks since Ava López cursed her coven, extinguishing any chance they had of restoring their magic. But as Ava and her vampire nestmates try to rebound from the chaos she caused, she discovers the war hasn't ended.
The humans of Darkhaven are suspicious of recent events, and a mysterious note etched in the ashes of tragedy shakes Ava to her core. On top of everything, she is forced to rely on information provided by a newcomer-a fire witch hot on the trail of a particularly malicious rogue vampire. The very same who may well be responsible for upending Ava's life.
