While one of the books will be an autobiograhy, to be released later this year, the other will come out next year coinciding with their tour. Both the books will be published by HaperCollins, reported Contactmusic.
"(It will bring fans) even closer to the band by telling their story in the kind of depth we've not seen before," said Natalie Jones, Publishing Director.
"It's a hugely exciting departure from the books we've published with the lads so far," Jones added.
The 'What Makes You Beautiful' singers have already released four books, 'One Direction: Forever Young', 'One Direction: The Official Annual 2012', 'Dare to Dream: Life as One Direction' and 'One Direction: Where We Are: Our Band, Our Story: 100% Official', since shooting to fame on talent show 'The X Factor' in 2010.
