Fed up with her wild behavior, sixteen-year-old Lex's parents ship her off to upstate New York to live with her Uncle Mort for the summer, hoping that a few months of dirty farm work will whip her back into shape. But Uncle Mort's true occupation is much dirtier than shoveling manure. He's a Grim Reaper. And he's going to teach Lex the family business.
She quickly assimilates into the peculiar world of Croak, a town populated by reapers who deliver souls from this life to the next. But Lex can't stop her desire for justice--or is it vengeance?--whenever she encounters a murder victim, craving to stop the attackers before they can strike again. Will she ditch Croak and go rogue with her reaper skills?

Cram ten hormonal teens into a spaceship and blast off: that's the premise for the ill-conceived reality show Waste of Space. The kids who are cast know everything about drama--and nothing about the fact that the production is fake. Hidden in a desert warehouse, their spaceship replica is equipped with state-of-the-art special effects dreamed up by the scientists partnering with the shady cable network airing the show.
And it's a hit! Millions of viewers are transfixed. But then, suddenly, all communication is severed. Trapped and paranoid, the kids must figure out what to do when this reality show loses its grip on reality.

Lex, a teenage Grim Reaper, has the power to Damn souls, and it's getting out of control. Her boyfriend, Driggs, is dead . . . sort of. She's a fugitive, on the run from the maniacal new mayor of Croak and the townspeople who want to see her pay the price for her misdeeds. Uncle Mort rounds up the Junior Grims to flee Croak once again, but this time they're joined by Grotton, the most powerful Grim of all time. Their new mission is clear: Fix his mistakes, or the Afterlife will cease to exist, along with all the souls in it.
The gang heads for Necropolis, the labyrinth-like capital city of the Grimsphere. There, they discover that the Grimsphere needs a reboot. To do that, the portals to the Afterlife must be destroyed . . . but even that may not be enough to fix the damage. Things go from bad to worse, and when at last the fate of the Afterlife and all the souls of the Damned hang in the balance, it falls to Lex and her friends to make one final, impossible choice.
