According to [[Black Library(BL Publishing)|Black Library]]'s [[Horus Heresy Series ]] editor [[Laurie Goulding]], "Garro is not a collection of short stories - it's James Swallow's full novelisation of Nathaniel Garro's story arc, something we've previously only seen (in part) in the audio dramas and novella. There are new and extended scenes, whole new chapters in fact, making this just about the most definitive exploration of the founding of the [[Knights Errant]], and everything that comes after."{{Cite This}}
