"The boy has no powers," they claimed.

A disappearing gold mine. An old family secret. An army officer carrying a grudge spanning two generations.

As a small time reporter at the local newspaper, Shen Yu already had enough on her plate. Biased managers, check. Long, brutal work hours, check. The department beauty snatching her big story opportunity, check. But now another problem has reared its head and it comes packaged in a young and attractive military officer. He is on the hunt for some legendary space gold and he will get her to help him, whether she likes it or not.

Secrets are abound and Shen Yu soon finds that not everything is not as simple as it seems. Even her own past becomes questionable the more time she spends on the quest. Events from decades ago are rising up to haunt her and she needs to find out the truth before it’s too late. If only she had a better partner.
