The Valley of the Angels by Benjamin Bishop

A kingdom in ruin. A traitor in the midst.
A banished warrior must rise again.

Chaos roams rampant in Eretz. The once majestic kingdom of the angels, a vibrant city of floating buildings and golden streets, now lies broken and tarnished. The king and queen have gone into hiding after losing their son, Prince Go’el, in The Great War, locking themselves inside their tower, abandoning their subjects to the darkness overtaking the land, all because a traitor revealed the secrets of the angels to those once trusted.

Banished angel, Mikha’el, is blamed for the devastating loss. As shamed wanderers, Mikha’el and the remaining Archangels doubt of return. When Mikha’el begins to have dreams of a new war, threatening to end everything, he knows the traitor is not finished, and he fears he may be powerless to help. But when Mikha’el has a second dream, revealing the prince is still alive, Mikha’el begins to realize his dreams may be the key to saving Eretz, even though they also foretell his own death.
