sunny boy books

After a series of complicated subway line transfers, Isaac stumbles into the Underside, a fantastical parallel world inhabited by a hodgepodge of overpowered beings. He’s saved by the “god” of this world, Lilith, who decides to implement a stat system to save the Underside from further property damage. Four years later, this system is (roughly) in place, and Isaac is the unfortunate soul tasked with keeping it updated.
