On planet Serabim there are two types of people: humans and Angels. When humans first arrived on Serabim, the natives welcomed them ... as long as humans stuck to the low grounds and left the aeries and the Angels alone. But something changed. Angels are murdering humans at an alarming rate, leaving their mutilated bodies on public display. In horror, the humans call upon their local Rider for justice. All is not as it seems on idyllic Serabim, as Captain Zala Lei and her Rider, Xander Lodai, will soon discover. The Rage of the Angels may indeed be something entirely more human.
