Our favourite fiction out in paperback this week: Terry Pratchett, Richard Armitage,

STROKE OF THE PEN by Terry Pratchett (Penguin £9.99, 256pp) 

As a young journalist working for the Bath & West Evening Chronicle, Pratchett wrote a series of short stories under the pseudonym Patrick Kearns.

 After becoming a best-selling author with his Discworld series, he told his publisher that he ‘deliberately forgot’ about his early stories, and they were thought to be lost.

But they were rediscovered with the help of dedicated detective work, and this delightful book brings together 21 early stories with an introduction by Neil Gaiman.

Pratchett’s distinctive wit and invention are already evident in these charming miniatures, from a hapless caveman whose brilliant inventions keep going wrong, to a group of rebellious ghosts determined to foil a plan by the pompous Minister for Nuisances to demolish their haunted castle.

GENEVA by Richard Armitage (Faber & Faber £9.99, 256pp) 

Sarah Collier, Nobel prize-winning neuroscientist, has been suffering from confusion and memory loss, so when a scan confirms early-stage Alzheimer’s, the last thing she wants to do is attend a medical conference in Geneva.

But a biotech company, the Schiller Institute, has invited her to endorse their latest miracle product – a tiny implant that could reverse the effects of dementia.

Meanwhile, pushy science blogger Terri Landauer is angling for an exclusive interview with Sarah.

Featuring a suave CEO, a sinister Russian head of security and a life-or death pursuit through the snowy Swiss landscape, the debut thriller by Spooks and The Hobbit actor Richard Armitage is a fast-paced switchback ride of drama, deception and deadly jeopardy.

THE UNFINISHED BUSINESS OF EADIE BROWNE by Freya North (Mountain Leopard Press £9.99, 448pp) 

The Unfinished Business of Eadie Browne is available now from the Mail Bookshop

When she was a little girl, Eadie thought her world was perfect. Not until she started school and was bullied by her nemesis, Patrick Semple, did she think there was anything eccentric about her family.

But her friends Celeste and Josh protected her until they went their separate ways to university. Studying in Manchester during the 1980s, Eadie enters a vibrant drug and music-fuelled world into which her past suddenly comes crashing.

The latest novel by best-selling author Freya North is a poignant coming-of-age tale, steeped in nostalgia for the bittersweet years between teenage turbulence and adulthood.
