The Crimson Moth Tome 2
The Rebel Witch

Rune Winters is on the run from the republic who condemned her and the boy who betrayed her. Her only ally is the unlikeliest one : Cressida Roseblood, the deposed queen intent on taking back what she thinks is hers - the crown, the country, and Gideon Sharpe. Gideon will not allow the terrors of his past to rise again, even if this means hunting down the witch who holds the key to Cressida's return ...
and Gideon's heart. And he will stop at nothing to find her. Rune Winters will meet her end. Even if it ends him too.
