Melerom Leads the Dance — C.M. Simpson

When Melerom escapes the aftermath of his people's massacre of the humans on Jehornak, he sets himself up as a wealthy wanderer on the Odyssey luxury liners, and acquires the one thing every gentleman needs -- a valet -- but when his valet begins showing unusually perceptive spurts of initiative, Melerom realises the man is not everything he seems. The only question is, can the man be trusted to help him survive multi-billionaire, Frederico Coleman's, next party, or betray him?
