Thorns — Kate Avery Ellison

Lia Weaver went against everything she'd ever known when she risked her life to help a Farther fugitive named Gabe escape from the Aeralian soldiers, and her life changed forever. And the Frost changed, too -- the Farthers have taken over her village, a new group of vigilantes calling themselves the Blackcoats are making plans to overthrow the Farther occupiers, and the Thorns are seeking for her to join them. Lia seeks to fight back against the evil and injustice that has swallowed up her home, but danger lurks at every turn. The monsters that dwell in the deepest regions of the Frost are growing bolder and more dangerous every day, a Farther noble takes up residence in the village on a mysterious mission, and Lia discovers even more secrets embedded in her past. As the frozen world of the Frost grows even more perilous, can Lia survive?
