The Free Navy - a violent group of Belters in black-market military ships - has crippled the Earth and begun a campaign of piracy and violence among the outer planets. The colony ships heading for the thousand new worlds on the far side of the alien ring gates are easy prey, and no single navy remains strong enough to protect them.

James Holden and his crew know the strengths and weaknesses of this new force better than anyone. Outnumbered and outgunned, the embattled remnants of the old political powers call on the Rocinante for a desperate mission to reach Medina Station at the heart of the gate network.

But the new alliances are as flawed as the old, and the struggle for power has only just begun. As the chaos grows, an alien mystery deepens. Pirate fleets, mutiny and betrayal may be the least of the Rocinante's problems. And in the uncanny spaces past the ring gates, the choices of a few damaged and desperate people may determine the fate of more than just humanity.

Partners now in marriage and in trade, Lady Julia and Nicholas Brisbane have finally returned from abroad to set up housekeeping in London. But merging their respective collections of gadgets, pets and servants leaves little room for the harried newlyweds themselves, let alone Brisbane’s private enquiry business.

Among the more unlikely clients: Julia’s very proper brother, Lord Bellmont, who swears Brisbane to secrecy about his case. Not about to be left out of anything concerning her beloved—if eccentric—family, spirited Julia soon picks up the trail of the investigation.

It leads to the exclusive Ghost Club, where the alluring Madame Séraphine holds evening séances…and not a few powerful gentlemen in thrall. From this eerie enclave unfolds a lurid tangle of dark deeds, whose tendrils crush reputations and throttle trust.

Shocked to find their investigation spun into salacious newspaper headlines, bristling at the tension it causes between them, the Brisbanes find they must unite or fall. For Bellmont’s sake—and more—they’ll face myriad dangers born of dark secrets, the kind men kill to keep��.
