As a girl walks home from school, she enjoys watching people with their dogs, knowing that while some seem mismatched, all are best friends.

When a young girl learns that the bullfight prize is her favorite food, churros, she decides to become a matador.

Told from separate viewpoints, Chess, Emma, and Finn Greystone, ages twelve, ten, and eight, investigate why their mother went missing and uncover their ties to an alternate world.
