Aiko is a courageous astronaut, specially trained to brave the extremes of space. The whole of humanity is counting on her success. But on a planet that shows signs of life, something goes awry, and when she wakes up, she finds . . . a pack of dogs? And . . . they can talk?

Descended from the valiant astro-dogs who first traveled in space, these canines have cut off all contact with Earth. They've found a new planet where they can live, far from humanity and their former masters. (Yes, that doesn't explain how they can talk, but that's a little complicated, so let's move on.)

Aiko is delighted. This discovery will make her the most famous astronaut on Earth! The dogs are . . . less delighted. "Finish your lunch," they say. "We need to walk you before your bedtime." They're going to keep her prisoner on their planet rather than let humanity find them again.

Can Aiko find her way home? Can the dogs protect THEIR home? Dear reader, we think you'll enjoy finding out!
