When King Edward 1st of England built Grogen Castle in Wales, he proclaimed it the strongest fortress in the British Isles; impregnable to assault, armed with devices so fiendish that would-be attackers would die in multitutdes. But the Welsh have had enough of English tyranny. Armed with druidic magic and an ancient, mystical artefact, they summon an army to their banner even the supersitious medieval world could never have imagined. Soon, Grogen Castle finds itself beseiged by forces forged from rotten bone and raddled flesh. Just how long can this Strongold hold out against the zombie horde?
