Hunters and Half-Bloods

Kronos blamed Percy Jackson for his defeat. If it weren't for that damned son of Poseidon, he would be in power. So what did the Lord of Time do? He went back in time. Way back. Not to the moment of his downfall, no, not even to the start of the war. As far as Kronos was concerned, his defeat was sealed the moment Percy Jackson was born. So he made sure the boy would never be brought into this wretched world... by eradicating his entire mortal bloodline.

But the Greek pantheon isn't the only domain affected by this. A shockwave tears through the fabric of reality-across this world, and all others. And as fate would have it, a new hero rises... alongside two monster-hunting brothers with a taste for danger and a habit of saving the world.
