Seven of Infinities
Aliette de Bodard2020

Vân is a scholar from a poor background, eking out a living in the orbitals of the Scattered Pearls Belt as a tutor to a rich family, while hiding the illegal artificial mem-implant she manufactured as a student.
Sunless Woods is a mindship—and not just any mindship, but a notorious thief and a master of disguise. She’s come to the Belt to retire, but is drawn to Vân’s resolute integrity.

When a mysterious corpse is found in the quarters of Vân’s student, Vân and Sunless Woods find themselves following a trail of greed and murder that will lead them from teahouses and ascetic havens to the wreck of a mindship--and to the devastating secrets they’ve kept from each other.
