Dragon's Source: Alveria Dragon Akademy, Part III

The greatest enemy is the one within.

Prince Kai Afkarr-Younger hides a dangerous secret—he’s been infected with the Nightmare Plague. Exhausted from battle and illness, he must force himself to stay awake or risk spawning yet another monster attack on the already beleaguered city; an impossible undertaking without the strength of his tamer.

Mari Asadottier will do whatever it takes to keep Kai’s infection secret from Alveria’s scheming Council. Without the power she offers through their bond, he’ll never make it through the coronation ceremony in his weakened condition. And without the strong leadership only Kai can provide, Bellsor will devolve into pandemonium.

But their efforts to protect Bellsor are hampered when Kai collapses shortly after being crowned, spawning the deadliest monster of all. Driven to defeat what he’s created, Kai nearly loses himself in a rogue animalistic frenzy. Only Mari’s persistence brings him back from the brink, and sets him upon the path to discovering Chaos’s nightmarish plan to destroy the Sources of Magic.

If they want any hope of defeating Chaos and protecting magic, Kai and Mari must hunt down and save the Primal Sources of Magic before they are gone forever—and Chaos reigns supreme.
