Tiffany Aching, the boldest heroine ever to swing a frying pan against the forces of evil, is beginning her apprenticeship in magic. She expects to work hard, learn spells, and become a witch. She doesn't expect to find herself doing chores, caring for the careless, and trying to outthink an ill-tempered nanny goat. There must be more to witchcraft than this!

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.

Sir Terry Pratchett's final Discworld novel, which features the witch Tiffany Aching.

Tiffany Aching has spent years studying with senior witches, and now she is on her own. As the witch of the Chalk, she performs the bits of witchcraft that aren't sparkly, aren't fun, don't involve any kind of wand, and that people seldom ever hear about: She does the unglamorous work of caring for the needy. But someone - or something - is igniting fear, inculcating dark thoughts and angry murmurs against witches.

It begun as a sudden strange fancy...Polly Perks had to become a boy in a hurry. Cutting off her hair and wearing trousers was easy. Learning to fart and belch in public and walk like an ape took more time. And now she's enlisted in the army, and searching for her lost brother. But there's a war on. There's always a war on. And Polly and her fellow recruits are suddenly in the thick of it, without any training, and the enemy is hunting them.

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.

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.

The Ankh-Morpork Post Office is running like...well, not at all like a government office. The mail is delivered promptly. Postmaster General Moist von Lipwig, former arch-swindler and confidence man, has exceeded all expectations - including his own. So it's somewhat disconcerting when Lord Vetinari summons Moist to the palace and asks, "Tell me, Mr. Lipwig, would you like to make some real money?"

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.

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).

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.

The show must go on, as murder, music, and mayhem run riot in the night. The Opera House, Ankh-Morpork, is a huge, rambling building, where innocent young sopranos are lured to their destiny by a strangely familiar evil mastermind in a hideously deformed evening dress.

What could be easier than preventing a servant girl from marrying a prince, especially for three clever witches? But Granny Weatherwax, Nanny Ogg and Magrat Garlick face more than they bargained for when they journey to the distant city of Genua. For one thing, their power is limited to Mrs. Gogol's weak voodoo spells, a one-eyed cat, and a secondhand magic wand that works only on pumpkins.

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.

Sam Vines is a man on the run. Yesterday, he was a duke, a chief of police, and an ambassador. Now he has nothing but his native wit and the gloomy trousers of Uncle Vanya. And if he can't make it through the forest to civilization, there's going to be a terrible war. But there are monsters on his trail. They're werewolves - and they're catching up. Sam Vimes is out of time and already out of breath....
