Crow/raven in the title, main character is a girl, book starts with her running from a group of boys chasing her, unclear if they’re trying to kill her, a yearly event, then there’s a flashback type thing to her mother eating (being weird eaten?) someone

I believe it was release in the span of one to five years ago. I think it had a bird on the cover and either crow or raven in the title.
