Before the Flood

The Bible called them the sons of God.

They were never angels. They came from the stars.

When archaeologist Dr. Elias Kane uncovers a sealed cylinder beneath the ruins of Göbekli Tepe - the oldest human structure on Earth - he finds a text that rewrites everything humanity thinks it knows about its own history. The so-called Nephilim of Genesis were not mythological beings. They were extraterrestrial conquerors who visited Earth before recorded history, genetically engineered a hybrid warrior race, and nearly wiped out the human species.

They were driven back once.

Now they have returned.

As cities fall under coordinated attacks that no military force can stop, former special forces operative Mara Velez discovers that the ancient monuments scattered across the globe - the pyramids, the megalithic circles, the underground chambers - were never religious sites. They were weapons. Built by the survivors of the first war. Waiting to be used again.

But the only way to stop the invasion may lie with Asher - a hybrid giant who was bred to destroy humanity and is beginning to question everything he was made for.

Before the Flood is a breakneck archaeological thriller that asks: what if every ancient myth about gods, giants, and the great flood was the last war humanity almost lost - and the enemy never really left?

Perfect for fans of James Rollins, Matthew Reilly, and ancient aliens thrillers.
