There are over 370 books in the Warhammer 40k series. As veteran Warhammer author Graham McNeill explains, the books offer a chance to introduce complexity and depth, while respecting the Lore the fans know and love.

He introduces his top five choices, and gives us a glimpse of the writers’ world – of group workshops, complicated timelines, constant correspondence, and friends for life.

Isaac Asimov is a sci fi icon who wrote over four hundred books – which can make it hard to know where to begin.

Whatever genre you love, it can be made steampunk, argues ‘The Steampunk Scholar’ Mike Perschon.

When The Day of the Triffids introduced John Wyndham to the world, it was a smash hit because of his keen interest in humanity, says his biographer Amy Binns. She talks us through her top five Wyndham books, stories that explore motherhood and feminism, religion, loneliness and uncertainty – but always wrapped in warm, witty, page-turning adventures.

Low-stakes 'cozy' fantasy is very popular right now, says the bestselling author TJ Klune—and as a result it's a very exciting time to be working in the genre. Here he recommends five cozy fantasy novels, all with magical worlds to get lost inside: from moving castles to coffee shops at the end of the world.

By telling alternative histories, we can run thought experiments that shed new light on our own timeline. ‘Master of alternate history’ Harry Turtledove talks us through his five favourites – and considers why alternate history pre-dates conventional sci fi, why some historical changes make for better drama than others, and how the micro-histories of our own lives are radically shaped by chance.
