Dante “the Fox” Hollow knows this all too well—he’s a low-tier Harvester, scraping by on leftover drops of divinity while the real monsters take everything. Quick with a blade, quicker with his mouth, and always one step ahead of trouble, Dante dreams of a day when he won’t have to run anymore.That day comes when he stumbles upon the abandoned resting place of a god—not just any god, but the Trickster himself. A legend, a liar, a master of chaos. And Dante? He’s just stupid enough to take a sip.Now, the hunger is setting in. The whispers in his head are getting louder. The gods are watching, and some aren’t happy. Dante’s power is growing—too fast, too dangerous—but the higher he climbs, the closer he gets to losing himself.Because there’s one rule every Harvester knows: the more you steal from the gods, the less of you remains.And Dante? He plans to steal everything.
