The war between Heaven and Hell [heck as the angels call it] continues after over 15 years of battle, death, and betrayal. It started by demon spies invading the royal palace and soon the demons killed Queen Titania and King Sizar of the angels. Their daughters Hope and Scarlet are the only royals left to lead the rest of Heaven into battle. The only problem is that Hope was born with no wings. Without wings, she is disrespected by her own sister and most of Heaven. Wings were required for almost everything in Heaven and Hope is the only angel in centuries to be born without them. Hope soon gets kicked out of the palace by her sister and is on her own, with no way to protect herself.

Near the border between Heaven and Hell, a wingless angel goes, and a harmed demon escapes death. But what happens when both meet at the peak of the war?
