Daemon World (Warhammer 40,000 Novels)

Deep within the twisted hell-storms of the warp lies the daemon world of Torvendis, a planet damned by the dark powers of Chaos. Savage battle has raged for so long that the very bedrock of the planet is formed from strata of crushed bodies. The arrival of a mysterious stranger threatens to upset the balance of power currently held by Lady Charybdia, princess of Slaanesh, precipitating a bloody revolution. But are the stranger's motives as straightforward as they appear or do the fickle powers of Chaos have one last trick to play?
