Fireblood

Ruby has beaten the Frost King and melted his throne, but the Minax that was bound inside it is loose. It haunts her kingdom and the people she loves, and she needs to learn how to stop it.

The answers may lie to the south in Sudesia, the country of the Firebloods. It holds the secrets of Ruby's powers and her past. Arcus, the king who loves her, warns her against going, yet she leaves with Kai, a roguish Fireblood.

In Sudesia, the Fireblood queen distrusts outsiders. To earn her trust, Ruby must master her control of fire and pass a series of trials. Only then can she reach the knowledge that might defeat the Minax, which draws nearer with each passing day.

This is the second book in the Frostblood series, a fantasy with a fast, action-driven pace. Ruby is pulled between her fiery homeland and Arcus, and time alone with Kai adds a spark of attraction that clouds her judgement about whom to trust. The fate of both kingdoms rests with her.
