Reign From Heaven - War of the Gods, #2

The Greek Olympians have returned. Greek Olympian gods Hermes and Herakles have escaped the darkest realms of Hell and now live among their new extended family in a creepy town called Saraday. Finally free from servitude, they can train their new little step-brother to be a real demi-god. But the archangels of Heaven have noticed that Hell has gone suspiciously quiet after the Greeks escaped. They make a bold decision: seize the Earth and claim it in the name of God, glory, and goodness.
However, doing so will put events into motion that could destroy the same humanity the angels claim to protect. It's Olympians versus angels as they fight to keep the Earth realm safe from utter destruction.
