The Swedish gamer, who has more than 37 million YouTube subscribers, will release This Book Loves You in October.
The 250-page illustrated book promises “indispensable advice and inspirational quotes”.
Kjellberg, who is best known by his online alias PewDiePie, has the most subscribed to channel on YouTube, overtaking Rihanna’s channel to become the most viewed of all time in 2014.
His videos generally feature him playing games while giving an on-screen commentary in the top left hand corner.
The 25-year-old, who lives in Brighton, said: “This book is a great chance for me to reach my audience in a new way. The original idea actually came from my fans via Twitter, so I really think they are going to love it.”
Ben Schrank, president and publisher at Penguin US’ Razorbill imprint, said: “With more subscribers than Taylor Swift and One Direction combined, Felix is without question one of the most influential stars of this generation.”
YouTubers Zoe ‘Zoella’ Sugg and Alfie ‘Pointless Blog’ Deyes both released best-selling books in the UK last year.
Sugg’s young adult novel Girl Online became the fastest selling book of 2014, but the YouTube star was later criticised for using a ghostwriter to help pen the novel.Reuse content
