A children’s adventure story where every puzzle is a computer science concept wearing a costume. The title is a joke about placeholder text, which sets the tone.
Lauren gets lost and has to think her way home through problems that turn out to be routing, recursion and the travelling salesman.
What it gets right is never naming the concepts while you are inside them. The reader solves the thing first and finds out what it was called later, which is the correct order and the opposite of how this is usually taught.
