Ever wonder what it would be like to live on the Moon? Just ask Aphrodite Kim, a teenage genius who was born on Luna and has lived there all her life. She knows TerraNova City well; in fact, she's a certified tour guide, making extra money guiding rich Earthworm tourists around the Lunar Free State's capital.

Now, however, she's starting a new business, Dragon Technologies, where she claims to be able to repair, refurbish, or improve just about any electronic or mechanical gadget—a service much in demand on Luna, where people don't want to pay the high cost of replacements imported from Earth.

Aphrodite has barely gotten the doors open when her first customer arrives, bringing what looks like a simple hack job on a common electronic device, just a little tweak that will make it do what the customer wants. Little does she know that a secret lurks in the gadget's software, a secret that will lead her down a dangerous path into the world of interplanetary espionage and intrigue.
