Tiffany Aching, the young witch from The Wee Free Men, A Hat Full of Sky, and Wintersmith is back in a new adventure featuring Discworld characters both familiar to fans (such as Tiffany, the Wee Free Men, Granny Weatherwax and Nanny Ogg) and new (meet Wee Mad Arthur, the Nac Mac Feegle on the City Watch whose only previous appearance was a brief cameo in Feet of Clay, and city witch Mrs Proust - a fabulous Pratchett creation).

Tiffany Aching put one foot wrong, made one little mistake... and now the spirit of winter is in love with her. He gives her roses and icebergs, says it with avalanches and showers her with snowflakes - which is tough when you're 13, but also just a little bit...cool.

Eleven-year-old Tiffany Aching wants to be a real witch. But a real witch doesn't casually step out of her body, leaving it empty. Tiffany does, and there's something just waiting for a handy body to take over. Something ancient and horrible, which can't die.

Up on the chalk downs they call The Wold, witches are banned - ever since the Baron's son vanished in the woods. Anyway, as all witches know, chalk's no good for magic. Nine-year-old Tiffany Aching thinks her Granny Aching - a wise shepherd - might have been a witch, but now Granny Aching is dead and it's up to Tiffany to work it all out when strange things begin happening.

To the consternation of the patrician, Lord Vetinari, a new invention has arrived in Ankh-Morpork - a great clanging monster of a machine that harnesses the power of all of the elements: earth, air, fire and water. This being Ankh-Morpork, it’s soon drawing astonished crowds, some of whom caught the zeitgeist early and arrive armed with notepads and very sensible rainwear.

Football has come to the ancient city of Ankh-Morpork - not the old fashioned, grubby pushing and shoving, but the new, fast football with pointy hats for goalposts and balls that go gloing when you drop them. And now, the wizards of Unseen University must win a football match, without using magic, so they're in the mood for trying everything else.

Rats! They're everywhere: in the breadbins, dancing across tabletops, stealing pies from under the cooks' noses. So what does every town need? A good piper to lure them away. That's where Maurice comes in. But he's only a cat (though one that talks).

It's an offer you can't refuse. Who would not wish to be the man in charge of Ankh-Morpork's Royal Mint and the bank next door? It's a job for life. But, as former con-man Moist von Lipwig is learning, the life is not necessarily for long. The Chief Cashier is almost certainly a vampire. There's something nameless in the cellar (and the cellar itself is pretty nameless), and it turns out that the Royal Mintruns at a loss.

Koom Valley? That was where the trolls ambushed the dwarfs, or the dwarfs ambushed the trolls. It was far away. It was a long time ago. But if he doesn't solve the murder of just one dwarf, Commander Sam Vimes of Ankh-Morpork City Watch is going to see it fought again, right outside his office.

Suddenly, condemned arch-swindler Moist von Lipwig found himself with a noose around his neck and dropping through a trapdoor into...a government job? By all rights, Moist should be meeting his maker rather than being offered a position as postmaster by Lord Vetinari, supreme ruler of Ankh-Morpork.

William de Worde, the accidental editor of Discworld's first newspaper, just wants to get to the truth. Unfortunately, everyone else wants to get at William. And it's only the third edition.

Mightily Oats has not picked a good time to be a priest. He thought he'd come to the mountain kingdom of Lancre for a simple little religious ceremony. Now he's caught between vampires and witches, and he's not sure there is a right side.

A man with no eyes. No eyes at all. Two tunnels in his head . . .It’s not easy being a witch, and it’s certainly not all whizzing about on broomsticks, but Tiffany Aching – teen witch – is doing her best.Until something evil wakes up, something that stirs up all the old stories about nasty old witches, so that just wearing a pointy hat suddenly seems a very bad idea.Worse still, this evil ghost from the past is hunting down one witch in particular.

Time is a resource. Everyone knows it has to be managed. And on the Discworld that is the job of the Monks of History, who store it and pump it from the places where it's wasted (like the underwater; how much time does a codfish need?) to places like cities, where there's never enough time. But the construction of the world's first truly accurate clock starts a race against, well, time for Lu Tze and his apprentice Lobsang Ludd.

Truth! Justice! Freedom! And a hard-boiled egg! Commander Sam Vimes of the Ankh-Morpork City Watch had it all. But now he's back in his own rough, tough past, without even the clothes he was standing up in when the lightning struck. Living in the past is hard. Dying in the past is incredibly easy. But he must survive; he has a job to do.
