A thousand years ago, Earth received an alien signal, inviting us to a perfect Earth like planet. A ship was sent to investigate it, but it vanished.
Today: Saki is born in the perfect city, where everyone is telepathic, and a computer takes care of all your needs. The only problem is, non-telepaths like Saki aren’t expected to live longer than fifteen years. Saki turns fifteen next week.
The perfect city is actually a perfect prison: No one can leave. Even the dead are imprisoned as ghosts in the desert. Saki finds the only way he can survive is if he can find the mythical City in the Stars. But is it even real?
