This time I’m going leftfield, with three books that are gloriously bonkers in very particular ways. ‘Early Riser’ takes place in an alternate reality, where each perilous winter, most of the earth’s population hibernates, ‘The Rearranged Life of Oona Lockhart’, shows us what happens when, every New Year’s Eve, Oona is transported to a different year of her life, moving backwards and forwards through time, and in ‘Bonk’, we learn about the real and surreal world of sex and science.
