Conn Iggulden made publishing history by topping the fiction and non-fiction hardback bestseller lists simultaneously with the first in his Genghis Khan series, Wolf of the Plains and the nostalgic How To manual he co-authored with his brother, The Dangerous Book for Boys. Subsequent instalments of Khan's Mongolian adventures sold millions, as did his series set in Julius Caesar's Ancient Rome.

Conn explains why for his latest series, which starts with the novel Stormbird, he has turned his attention to the Wars of the Roses; a turbulent time in British history, when the Houses of Lancaster and York battled for control of the throne.

From a touch of spring fever to the 'full glow and luxuriance of summer', we are now in the season of 'mists and mellow fruitfulness' as Keats would have it. Continuing our series looking at the influence of the seasons on literature, authors Horatio Clare and Susie Boyt discuss the creative power of Autumn.

Caroline Sanderson is a fervent advocate of non-fiction, which she says combines "the allure of a marvellous story with the telling of real things we really should know." She explores the best of the current crop of non-fiction works, gives suggestions for book groups and explains why she feels that non-fiction can do anything fiction does and often does it better.
