Noemi Vidal is a teen soldier from the planet Genesis, once a colony of Earth that's now at war for its independence. The humans of Genesis have fought Earth's robotic "mech" armies for decades, with no end in sight. After a surprise attack, Noemi finds herself stranded in space on an abandoned ship where she meets Abel, the most sophisticated mech prototype ever made--one who should be her enemy. But Abel's programming forces him to obey Noemi as his commander, which means he has to help her save Genesis--even though her plan to win the war will kill him. Together they embark on a daring voyage through the galaxy. Before long, Noemi begins to realize Abel may be more than a machine, and, for his part, Abel's devotion to Noemi is no longer just a matter of programming.
