The Girl Who Drank The Moon by Kelly Barnhill

A Newberry Medal Award winner. Description from the back of the book: Every year, the people of the Protectorate leave a baby as an offering to the witch who lives in the forest to keep her from terrorizing their town. But the witch, Xan, is really and gentle. She shares her home with the wise Swamp Monster and a Perfectly Tiny Dragon. Xan rescues the children and delivers them to welcoming homes on the other side of the forest. One year, Xan accidentally feeds a baby moonlight, filling the ordinary child with extraordinary magic. Xan decides she must raise this girl, whom she calls Luna, as her own. As Lina’s thirteenth birthday approaches, her magic begins to emerge with unprecedented consequences, just when it’s time for Xan to go collect another child. Meanwhile, a young man is determined to free his people by killing the witch. And a volcano, dormant for centuries, rumbles within the earth… Near read but has some damage to the corners.
