Warrior Princess #3: The Emerald Flame by Frewin Jones

The Emerald Flame of her people.

Branwen has finally accepted that the Shining Ones have chosen her to save her country from the Saxon invaders. But the next stage in her journey includes a seemingly impossible mission, and the path before her is filled with darkness and danger. Branwen is pushed to the brink of disaster, and with each step she takes, she is being pulled farther from the life she once knew—the life she still desperately misses.

Guided by the spirits, with both her fearless friend Rhodri and the dashing, sometimes maddening Iwan by her side, Branwen must overcome terrifying odds if she is to succeed in her quest. But a true Warrior Princess won't back down . . . even when an old enemy returns.
