Grey Knights (Warhammer 40,000: Grey Knights)Grey Knights (Warhammer 40,000: Grey Knights) by Ben Counter
Buy used from: £0.01
Gray Knights is a spetaciular Sci-fi book but with in the Warhammer 40.000 universe context it stands out. It covers important places and forces but its real strength lies in the plot itself.
Execution Hour (A battlefield gothic novel)Execution Hour (A battlefield gothic novel) by Gordon Rennie

Again a great plot based on a great game, this time Battle Fleet Gothic as well as Warhammer 40.000. One of the better commisioned novels.

Buy used from: £0.30
A good climax as a sequel to the Ultramarine Novels and Storm of Iron. It surpasses the prievious books by far (but you might want to read them first).
Storm of Iron (Warhammer Novels)Storm of Iron (Warhammer Novels) by Graham McNeill
Buy used from: £3.14
The top 4 are the best in their category but Storm of Iron has its merits and should be read before you read Dead Sky Black Sun, a lot of characters appear in both.
For the Emperor (Ciaphas Cain)For the Emperor (Ciaphas Cain) by Sandy Mitchell

Medium if not for its welcome humor. Fun read.

Malleus (Eisenhorn Trilogy)Malleus (Eisenhorn Trilogy) by Dan Abnett

Book number 2 in a series of 3. The best book in the series and you might as well read all 3 although this one is the best.
