Kanaahn, Arial, Arkas, Shooter, and Drakhart have been friends for years. In the harsh criminal landscape of the town of Kula, they've had to grow up fast, but they've pulled through by sticking together. Yet lately, a rift has grown between Drakhart and Kanaahn. Drakhart feels unheard, pushed aside by the group's self-appointed leader. Kanaahn can't understand why Drakhart has been lashing out and withdrawing from their friends.

Then Kanaahn finds five dragon eggs in a cave outside town. In one fateful hatching, these young vigilantes become the fabled Khaleeshir-humans bonded to dragons and entrusted with great magical abilities, guardians of man and dragon alike. They are also harbouring the most-hunted creatures in the entire country of Altimara.

The five friends must travel across a vast desert, train with a hidden dragon council, and delve into ancient magic to learn their destiny and prepare to face the greatest threat to the continent of Enayra in a thousand years: Tenebrae, the human-despising black dragon who perfected the forbidden Blood Magic. No one can be trusted. Every choice they make is a strain on their already endangered friendship. The further they dig, the closer they get to losing each other.

Some relationships you can't put off repairing without paying a steep price.
