Book: Fallen Hunted.
The Maraid, Book VIII, Chapter 4
After a string of defeats—at Amethyst, at Hygiea, arguably at Iris—Prince Uldren's Crows finally made headway against the Wolves' encryption. They quickly discovered a seemingly unimportant piece of information: the House of Wolves had incorrectly calculated the eccentricity of the asteroid Bamberga.
So Paladin Imogen Rife chased Drevis, Wolf Baroness, directly into Bamberga's trajectory. Drevis' ketch was destroyed, and both she and her High Servitor, Kaliks-4, were captured.
It was the first decisive Reef victory since the Scatter. But on her way back to Vesta with her captives, Paladin Rife was attacked at Pallas.
