Only the purest heart, a dragon's heart, can save them now.

After being injured while reversing the froggen's flood on Anavrin, Tambrynn travels to the depths of the mysterious Bloodthorn Forest for a cure. There she finds what she's looking for, but she also finds more trouble than she can handle. Thoron, her dark mage father, has found her and he's brought the Hulda, a villainous spirit Guardian, along as well. Tragedy strikes during the ensuing magical battle, leaving Tambrynn reeling from one loss closely followed by the death of a loved one. Shaken, Tambrynn barely manages to escape to her grandfather's mountain sanctuary to hide.

Burgeoning with power siphoned from dragon bones, Thoron is only a few steps behind her, making that sanctuary a prison. When unrest spreads across Anavrin, threatening all the Anavrinians again, Tambrynn must race to unlock the hidden power of her firebird abilities in order to defeat her evil father. But time is of the essence, and there's no way out of the mountain in sight.

With time running out, and hidden dangers around every corner, will a fairy tale and a secret pathway lead Tambrynn to find a true dragon's heart, the only power pure enough to take on Thoron's enhanced malevolent magic? Or will her father do what he set out to do since she was born-steal her abilities and destroy all that the Kinsman has created?
