Meet Piper Shaw. She's one of the Netherworld Paranormal Police Department's toughest. She's also an immortal, and she's got one hell of a chip on her shoulder.

Meet Reaper Payne. He's an actual reaper. Yes, one of those guys who ferries the dead. Unfortunately, he broke a rule of his order, and it was a doozy. His punishment is to dwell alongside the living for one hundred years.

They're both Retrievers in the PPD. Essentially, they hunt in the Overworld (a.k.a. topside) to bring back supernaturals who have overstayed their welcome.

Piper is clear about one thing: She does not want a partner.

They just became partners.
