The Hour of Our Death — Scarlett Parrish

She's been to hell and back…and he lives there. Samael didn't want to be sent back up to Earth, especially with so many other demons going missing, but his brother Azrael got drunk (again) and lost his scythe, leaving him unable to reap souls and Samael having to clear up his mess. Again. Eventually the scythe shows up in the possession of Portia Frost, who's been using it to off the demons she's been able to see all her life. At least now she can do something about them. Samael wants the scythe back but Portia refuses to hand it over without a fight. She's got a taste for spilling ichor and now? She's coming for Samael.
