Tales of Heresy (Horus Heresy) by Dan Abnett Review: A Rich Multi-Author Anthology of the 31st Millennium

Tales of Heresy is the tenth volume in Black Library's Horus Heresy series — a science fantasy anthology published in 2009 that gathers seven short stories set across the Great Crusade and the early period of the Horus Heresy. The contributing authors are Dan Abnett ("Blood Games"), Mike Lee ("Wolf at the Door"), Anthony Reynolds ("Scions of the Storm"), James Swallow ("The Voice"), Gav Thorpe ("Call of the Lion"), Graham McNeill ("The Last Church"), and Matthew Farrer ("After Desh'ea"). As Wikipedia's coverage of the series notes, the narratives fill gaps in the main sequence or add further detail about the Heresy and its key actors, covering periods that range from several decades before the conflict to roughly the timeframe of the eighteenth novel in the series.

The Horus Heresy is, as Wikipedia documents, a dark, far-future military space opera set in the fictional 31st millennium of the Warhammer 40,000 universe — a galaxy-spanning civil war within the nascent Imperium of Man. The series is an established, definitive component of Games Workshop's Horus Heresy sub-brand and authoritative source material for the entire Warhammer 40,000 shared universe. Titles in the series have frequently appeared on bestseller lists, and Tales of Heresy itself is marketed as book ten in what became a New York Times bestselling series. As the first anthology in the Horus Heresy line, it represents a structural departure from the preceding full novels — using the short-story format to broaden the canvas rather than advance a single narrative thread.

The anthology's central achievement, according to reader commentary on Thriftbooks, is its attempt to "weave together a more complete tapestry than the one occupied by the canonical HH novels," touching on elements of the Horus Heresy rarely foregrounded in the main sequence — including the Sisters of Silence and the strains placed on the Legions as the Great Crusade nears its end. That same commentary notes that almost all of the series' established authors contribute a story, lending the collection a sense of comprehensiveness. One reviewer on Thriftbooks highlights that Dan Abnett "keeps coming up with new angles and different parts of the overall story," and that none of the stories are unenjoyable. A reviewer quoted on Thriftbooks describes the collection as "fantastic" overall, with several standout entries alongside solid contributions across the board.

Several individual stories have drawn particular attention. Matthew Farrer's closing entry, "After Desh'ea," centers on the War Hounds Space Marine Legion and their newly discovered primarch: before they can follow him into battle, they must find a way to reach his sanity without ever raising a hand against him — a premise that sets it apart from straightforward military action. Graham McNeill's "The Last Church" ventures into philosophical territory rarely explored in the series. The diversity of tone and subject across the seven stories — from espionage and political intrigue to theological argument and primarch mythology — is, by the sources' account, a deliberate design feature of the anthology format.

As Thriftbooks reviewers note, not every story carries equal weight, and one or two raise the question of why they were included in the context of the broader series — though the same reviewers are clear that no story is without merit. By the nature of an anthology, readers looking for a continuous, driving narrative will find a different reading experience here than in the full novels. Tales of Heresy is designed for readers already invested in the Horus Heresy series; those without prior familiarity with the Warhammer 40,000 universe and its factions — the Space Marine Legions, the primarchs, the Emperor of Mankind — will find the stories harder to place and the stakes less immediate. The anthology format also means that shorter entries cannot develop characters or situations to the depth a full novel affords.
