A decades-old murder looms over the glamorous clientele of a high-end space hotel . . . while an unforeseen threat percolates in the service corridors. The guests are about to experience the hospitality they deserve.

Space Habitat Altaire is the premier luxury resort in low Earth orbit, playground of the privileged and the perfect location to host reunions for the Rochford Institute. Rochford boasts only the best: the wealthiest, most promising students with the most impressive pedigrees. Complete with space walks, these lavish reunions are a prime opportunity for alumni to jockey for power with old friends and rivals--and crucially, to advance their applications to live in an exclusive Mars settlement. Earth is dying, and only the best deserve to save themselves.

Aboard the Altaire for their 25th reunion, finance magnate Ava pursues the truth about her brother's murder during their senior year, which cast a dark shadow over their time at Rochford. Laz, ambassador and political scion, hopes to finally win Ava's heart. Sloane, collecting secrets to conceal his family's decline, angles for a key client. And Henry, heir to a healthcare empire, creates an unorthodox opportunity to get to Mars in a last-ditch effort to outrun a childhood secret.

While these erstwhile friends settle scores and rack up points, they fail to notice that other agendas are afoot at the Space Habitat Altaire, and their own futures aren't the only ones at stake--"the best" will soon regret underestimating those they would leave behind on Earth.
