Azuran

The second epic adventure in The Dragon Keeper Chronicles! A thrilling new fantasy world full of magic and dragons.
The dust has settled in the serpent battle. Crimson cares for a new dragon and life is peaceful. But it's a temporary peace and the Schorl serpents will return, drawn by the magic they steal from dragons.
When Azuran reappears, Crimson must convince him to rejoin dragon kind. Crimson wants to believe that Azuran is the same kind-hearted adventurous dragon she knew as a hatchling. But the closer she gets to Azuran, the more he seems to be hiding.
If Crimson succeeds, she will finally be able to forgive herself for failing Azuran as his keeper. If she fails, the dragon keepers will have an invincible obsidian dragon as an enemy and even Crimson's growing powers may not be enough to save them.
