This did hurt. It reminds me of my childhood and the people I grew up with.
"Hauntingly beautiful" suits the writing well.
Fairies resonate with me, and I've always been drawn in by monsters that didn't always make sense, whose motivations were unknown, who sometimes cause pain simply by nature. Creatures who are dangerous but not necessary malignant. To children, abuse is much like that.
The abrupt ending and lack of closure at the end left me feeling bereft, but that's how trauma is; you don't always get closure. You carry it forward, always, and even as your memories fade, the feelings are still there.
I wonder if Lily was one of her names.
