A Deadly Bloom - The Plague Bloom, #1

My name is Bryce Song, and for my entire life, I have lived in the shadow of a deadly Bloom that not only kills, but raises the dead. Since the plague's beginning, my people have journeyed toward our God's Promised Lands atop the backs of the Guardians. I have always wondered if we would reach our destination and felt helpless against the seemingly insurmountable odds. A great valley, filled with its Fallen peoples and their undead protector, separates us from our salvation.
The only chance of killing our monstrous enemy is to find a weapon, once wielded by our God. During the long journey, our heroes have been slain, and few are willing to embark on a quest to retrieve the holy relic. There's no question what I must do. I must journey to the last resting place of our God, and reclaim the weapon that will save my people from certain destruction.
