Poison Hearts by Jennifer Cody

Orlando:
No one intentionally starts out life trying to become a hired unaliver. Weeellllll, most people don’t. I come from a legacy of unalivers, though I think I might be the first one to make a career out of it. Accidentally. I wasn’t trying to; the opportunity just sort of showed up on my pillow, and being the conscientious unaliver that I am, I decided to investigate the mysterious invitation to a secret club.
Hello The Anonymous, and hello, Shannon.

Shannon:

Listen, you can buy your goodies off my menu or you can go to Bargain Bin Barry. His stuff costs half as much and works about half the time. Mine won’t fail you at a mission critical juncture, but I’m saving up for a Frankenstein machine, so it doesn’t come cheap.
What? Don’t spit on the dreams of mad scientists; I could be the one to discover the secret of life! After this dance, obviously. When a newbie to The Anonymous tells you he dances, you don’t just sit around hoping for the music to move you, you get up and take him to the dance floor.

Hello dreams come true, and hello, Orlando.
