Ravenor

Ravenor is the first novel in the trilogy Dan Abnett wrote as a kind of successor to his earlier Eisenhorn books, with a paralyzed psychic inquisitor running a cell of agents through the more political layer of the Imperium. The setup is dense, the cast is large, and the world-specific jargon is heavy in the early chapters. Push through.

Once the book locks in, it is some of the cleanest character-driven SF in the Black Library catalog. Ravenor himself is a wonderful protagonist precisely because he is locked in a chair and has to outsource almost every physical action. His agents (Kara, Patience, Nayl, others) are sharply drawn. The investigation, into a contraband drug being sold to the rich on a planet called Eustis Majoris, is more layered than the cover suggests.

Four stars. The Warhammer setting is a barrier for some readers and the prose density is a barrier for others. If you can clear both, the series rewards.
