Dot's mother is a famous space explorer. A famous missing space explorer. Missing like Dot-has-a-letter-from-the-Council-of-Human-Affairs kind of missing, not just the usual Mom-missing.

But Dot has a theory - and a plan. A theory that hinges on an old spacer's fairy tale and plan that relies on Dot's home-grown techno-baubles actually working (for once). But it is a real theory, and a real plan - and with the help of her trusty spaceship, Dot is going to bring her mother home.
