Teenage artist Millie Salmon discovers her family's used book store hides some powerful and interesting technology. In a funny and emotional adventure sprawling over planets, palatial estates, and interrupted farmers markets, Millie sews up holes in her family's history, struggles with secrets kept from her friends, and faces the terror of discovering her story and her universe are not what she thought they were.

All that, plus entombed ducks, brutal automated parking enforcement, and the hope that dad isn't making the family bake sale contribution.
