Blight

As the blight spreads, destroying the land, Cara’s new subjects turn on her, and Brendan and Drake are no longer there to help her. The Darksiders thought she’d be pliable, or maybe even a miracle-worker, and it’s not as easy to scrub away Sadler’s influence as she thought.
But Scarlet isn’t her only priority any more, and once the ceremony to swear her in as regent is done, it’ll be time for Cara to join forces with the kings, find a way to stop the blight, and prove to the fae that she can be the leader they need.
It took a Darksider to steal the throne; it’ll take a faery queen to keep it.
