Titus Groan by Mervyn Peake (Illustrated Penguin Modern Classics)

As the first novel opens, Titus, heir to Lord Sepulchrave, has just been born: he stands to inherit the miles of rambling stone and mortar that stand for Gormenghast Castle. Inside, all events are predetermined by a complex ritual, lost in history, understood only by Sourdust, Lord of the Library. There are tears and strange laughter; fierce births and deaths beneath umbrageous ceilings; dreams and violence and disenchantment contained within a labyrinth of stone.
