The group have signed a deal with HarperCollins to publish an official autobiography and One Direction: The Official Annual 2015 this year. Since releasing their first book in 2011, One Direction have sold three million copies worldwide across all formats. Their most recent book, Where We Are: Our Band, Our Story, spent five weeks at the top of the UK top selling list.
One Direction's first full joint autobiography, which will be released in September, will chart the former X Factor group's rise to stardom. According to HarperCollins: "Fans will discover how the boys have really felt over the last few years and their hopes and ambitions for the future. "The One Direction official autobiography will offer an incredible insight and intimacy to the band as never before and will bring fans even closer to Harry, Niall, Liam, Louis and Zayn."
Publishing director Natalie Jerome said: "The boys are an absolute pleasure to work with and always strive to deliver more to their fans. "It's a hugely exciting departure from the books we've published with them so far and there's a lot we're going to be doing that will make this an extra special experience for their loyal and devoted fans."
One Direction: The Official Annual 2015, set to be released in August, will contain photos, interviews and behind-the-scenes stories. In December, One Direction's third album, Midnight Memories, entered the US Billboard 200 at number one making them the only group to have their first three albums top the chart in their opening week. The album also went to number one in the UK and is the fastest-selling album for two years. This year the band embark on their Where We Are world tour, which includes dates in London, Manchester and Edinburgh.
