Bliss
There's a drug called Bliss wiping away memories in Feral City. A good-hearted young man, overwhelmed by a deathly sick child and distraught wife, makes a deal to become the personal hitman to three gods, killing those in their way and sending memories down the river of Oblivion in exchange for his family's well-being. Breaking Bad meets Neil Gaiman's Sandman in an urban fantasy unlike any you've ever seen.
