Shadow Captain
by Alastair Reynolds
Three months after the events of the novel Revenger, Arafura ('Fura') Ness finds herself in command of the Revenger. They break into a bauble in order to raid a cache of fuel. Barely escaping 'twinkle-heads' found inside, they retreat back to space. Surt and Adrana believe they are being followed by another ship, but Fura dismisses the concern. A book is found on board that documents the history of Occupations, but in addition there is a second timeline that hints at the existence of "Shadow Occupations".
When Revenger is struck by a photon storm, and it's decided they should travel to Wheel Strizzardy (a wheel world) on the outer reaches of the Congregation. While en route they are shot at by the still hidden ship trailing them, injuring Strambli. Arriving at Wheel Strizzardy the crew take on fake identities and bribe their way on to the station. Strambli is given over to the care of Dr. Eddralder. The crew meets with Mister Glimmery who is infected with the "glowy" like Fura, in his presences is an alien Crawly named Cuttle. Afterwards they are escorted by Sneed to another part of the wheel to find accommodations.The crew goes out to secure supplies, when they return they find Cuttle skulking near their rooms. Cuttle falls off a balcony and dies. Adrana and Prozor are accused of his murder by two Crawlies who show up on the scene. While on the station Fura manages to capture Lagganvor, a former associate of Bosa Sennen, who knows the whereabouts of The Miser, a bauble holding Bosa's cache of quoins.
Merrix is Dr. Eddralder's daughter and it being used by Glimmery to ensure he is not poisoned by the doctor's glowy treatments. But Eddralder ends up slipping a poison to Glimmery anyway. Eddralder leaves six syringes with an antidote, and joins the crew of the Revenger with Merrix, promising to radio back how to cure the poison. Lagganvor also goes along with the crew.
They travel to The Miser and once inside they find trams that hold more quoins than any of them have ever seen. As the trams near the central chamber the quoins begin glowing bright white and emit a scream that's heard inside their heads. They separate the trams and find that the quoins have been reset to seemingly random denominations. Returning to Revenger they discover the same is true throughout the 20,000 worlds, and fear that this financial event may cause the end of the Thirteenth Occupation.
Adrana works out that Lagganvor is Pol Rackamore's brother (Brysca) who took on the identity to get revenge for his brother's death. Their plan at the end is to go into hiding by pursuing the object that Adrana believes is orbiting the Old Sun at intervals coinciding with Shadow Occupations.
