Either an April Fools joke or maybe just my warped sense of humour!
I got a splash release email from Black Library offering the chance to download a free audio sample of a new horus heresy audio book - Sister of Silence

Written by Edward Knight with the tag line "Silence is golden" An audio book about an order that doesn't speak? Made me chuckle.
