Graveyard Shift by Angela Roquet

Lana Harvey is a reaper, and a lousy one at that. She resides in Limbo City, the modern capital of the collective afterlives, where she likes to stick it to the man (the legendary Grim Reaper himself) by harvesting the bare minimum of souls required of her. She’d much rather be hanging out at Purgatory Lounge with her BFF, the archangel Gabriel. But when a shocking promotion falls in Lana's lap, she learns something that could unravel the very fabric of Eternity. If the job isn’t completed, there could be some real Hell to pay.

“Charming and hilarious…Sookie and Betsy have some competition!”
