Looking for a haven, Astin Langlee went to the moon to escape the unforgiving rigors of poverty on Earth. Signing on for seven years of contract labor, he planned to work hard and make a place for himself. Called "Tinman' for his lack of observable emotion, he does just that, finding solace only in his conversations with Eddie, a sentient AI.
Finding love never crossed his mind.

Meeting his co-worker, Davis, Astin discovers that he cares more than his nickname suggests. Opening to the joy Davis brings in his wake, Tinman allows love to overcome his fear.

When the moon station is shut down by the uncaring LunaCorp, they head for Mars, only to find that home threatened by the same corporation.

Can Astin save his new home and those he loves, or will he lose all while taking a gamble none could envision?
