Brock is on a routine delivery flight when he receives a Valentine's Day message from a man who looks more like a fairytale merman than another human. But there's something instantly compelling about him.
The Company sends him and his three friends, committed couple Tolly and Emrys, and their sentient mechanical Broad to investigate the disappearance of Company men from the space station the Company is building. Instead they find a new world within a metal shell and that the Company is already there, subjugating its people.
Brock's valentine is Dyami, a prince who is a prisoner along with the rest of his family. The Company agents are Trenton and Annabelle, and the missing men are being used to mine diamonds.
Trenton offers to allow Brock and Dyami to be together but betrays his word, sending Brock and Emrys to the mines. He keeps Tolly, who was recognized as part of a eugenics experiment to create humans with enhanced abilities.
Brock and Emrys must race against time, not only to free themselves but reach Tolly before Trenton and Annabelle can destroy him completely.
