Monster Made by A.V. Blackmoor

Everything about Piper Day belongs to me. She’s mine to hate, mine to bully, mine to own.
I should really stay away from her. But that’s hard to do when I keep waking up outside her house with no memory of how I got there.
I can’t decide if I want to kill her or possess her. All I know is that if anyone else touches her, he’s dead.
Then she starts digging into the secret society I belong to. She has no idea what she’s walked into. I wish I could be the person to keep her safe. But Piper Day will never be safe from me.

Tropes: bully, stalker, obsession, psychopath, morally black MMC, bookworm FMC, enemies to lovers
A dark, high-heat novella featuring Quill and Piper, set before the Monster Duet.
