Rosemary's pov:
Watching Avery have fun on the swing was definitely enjoyable. He's always had this air like he's not allowed to… I didn't think that kid was capable of smiling, but I could swear I saw one drawn on his lips.
Nevertheless, Avery's smile was not all I got out of my conversation with Nathanael.
Since, I was able to learn that harpy's claws can be obtained through two methods; synthesis as well as extraction.
According to Nathanael, Harpy's claws as a substance is a sort of venom secreted by vampires in tremendously low doses. The goal is to render their prey loopy and defenseless for them to feed in peace.
