Request #396 From graciem012

Okay so this book I read when I was like 12 and I’m SO POSITIVE it was called Psyche, about a young girl who goes to stay with her extended family on their farm, and ends up on a quest to save the farm from the rat king in the sewers and she has a sword and fights at the end. But I can’t find it anywhere and now I’m doubting that it was called psyche even though I was SO positive If anyone can help me I will love u forever
