Rosario
My alchemy diploma is as useless as the men I’ve been dating.
Blacklisted from the industry, I took the job nobody else would touch: glorified assistant to the Divine Executioner—God’s favorite assassin. He tortures with flair. Kills with a smile… but it’s his longing stares that leave me truly terrified.

This gig is only temporary. Until I save up enough to start my own alchemy boutique. But the Executioner is a ruthless immortal beyond mortal laws, said to tally corpses and lovers in equal measure.
I have a bad feeling he will never let me go.

The Executioner
Humans think I’m a psychopath. I don’t think about them at all.
My routine keeps me sane. Seven days per prisoner. Feed on fear. Dispose. Paperwork. Repeat.
But ever since Rosario became my operations manager, I’ve been lovestruck. For the first time in centuries.
I watch her sleep. I plan our life together. I hear the bells toll.

She may be trying to outrun her past, but she will never outrun our future.
Till death do us part is a wonderful notion… especially when you’re immortal.
