Sixteen books and three years after The Damnation of Pythos, David Annandale’s second Horus Heresy novel is Ruinstorm, book forty-six in the series overall. Signalling the end of the Imperium Secundus arc (therefore NOT to be read before Angels of Caliban), it sees the Triumvirate of primarchs – Guilliman, Sanguinius and the Lion – setting out from Ultramar to defy the Ruinstorm and find their way to Terra. Each chooses an approach based on their own approach and inclination, but can they find a way through? Most 40k fans know the answer to that, but now we can find out just what happened and why.
