Okwu, the outcast by association. Always less, and nothing more. It's the only way Kiyoa Apuzzo is known on the Temples, and it's all his brother's fault. He's about to make his debut as the BookKeeper's apprentice, a powerful position that could rewrite his destiny. But it all goes wrong when his brother makes an unexpected visit.

Steal the Book of Sky Diamonds and I'll make you a hero. It's an offer Antonius 'Naias' Apuzzo can't refuse, especially when there's nothing he wants more than to be a hero. After ten years of banishment, Antonius returns home to the Temples to fulfill the Patron's request, and steals the book whose magic the Temples rely on. In his attempt, the Book's magic is unleashed, casting the world into destruction.

Before their world is torn apart, Kiyoa and Antonius have no choice but to work together to restore the sacred Book, a quest where they'll learn what it means to be heroes, but also brothers.
