Finally reunited with his angel warrior sister and brother and happily mated to Ana, Appolion thought that his life was all set. Unfortunately for him, nothing has ever gone that smoothly. Before he can even settle into his new life, he finds himself under attack again and this time it's from the supposedly good guys. He is stunned and ticked to find out that there are just as many angels as demons that would like to see him destroyed.

All is not lost though, the Chief of Archangels, Michael is determined to protect The Order. But in doing so, he sets off a chain of events that will change all angels forever and set off a war of epic proportions.
