The Wolf at Memory's End

Kasumi Kuromine has always been a girl who speaks her mind—and she butts heads with her classmates for it. But when the fierce yet openhearted middle schooler tumbles down a hillside while trying to save one on a school field trip, she wakes up in an impossible place: a mysterious inn where lost memories can be found. What she discovers there…promises to change everything she thought she knew about herself.
