Mare Barrow may have the red blood of common folk, but her rare Silver ability to control lightning has made her a dangerous weapon—and a target for the royal court's control.

Betrayed by Maven, the prince she once trusted, Mare discovers she's not the only one of her kind. There are others—Red bloods with Silver abilities—hidden across the land.

Now, hunted by Maven, who has seized the throne and become a vindictive king, Mare embarks on a perilous journey to find and recruit these new allies to join her fight against oppression.

But as the battle intensifies, Mare faces a dark path. The line between hero and villain blurs, and she risks becoming the very monster she seeks to destroy.

Will she crumble under the weight of the rebellion's cost, or has betrayal forged her into something unbreakable?
