A man with no eyes. No eyes at all. Two tunnels in his head . . . Somewhere - some time - there's a tangled ball of evil and spite, of hatred and malice, that has woken up. And it's waking up all the old stories too - stories about evil old witches . . . I Shall Wear Midnight is the fourth Discworld title to feature witch Tiffany Aching and her tiny, fightin', boozin' pictsie friends, the Nac Mac Feegle (aka The Wee Free Men).
