The latest Space Marine Battles novel – The World Engine – is Ben Counter’s second in the series and promises to be about as epic a story as it’s possible to be. The titular World Engine is a mobile planet, a vast and apparently indestructible necron construct that has been marauding through Imperial space and devastating systems with impunity. With few options remaining, the entire Astral Knights chapter launches a suicidal assault, crashing their battle barge directly into the planet in a last ditch attempt to stop the World Engine. The Space Marine Battles series is built on the premise that the stories told are enjoyable, entertaining and fun, and with such a ridiculously over the top concept this should deliver all three in spades.
