Leona Lewis. Photos by Dean Freeman.
It's out now!
Leona's become a global superstar since winning the X Factor in 2006, but what was she doing before she entered the competition? And what's life really like when your dreams of fame and success come true?
These are just some of the questions Leona sets out to answer in this illustrated autobiography.
It's really interesting to find out what goes on during the X Factor from a contestant's point of view, especially when Leona talks about her relationship with the show's most feared judge, Simon Cowell.
And finding out about Leona's attempts to make it as a singer before she entered the competition will give hope to any struggling wannabes out there. Top tip - you need to be REALLY determined and prepared to work hard!
But don't worry if you're not that into reading, there are LOADS of pictures of Leona's whirlwind road to stardom over the past couple of years too.
Any weak bits?
More than half of the book is photos, which may disappoint hardcore Leona fans who want to know more about their idol, but overall, it strikes a good balance.
It's interesting for fans, but most people will probably pay more attention to the photos.

"This book is a must read, I highly recommend it. It speaks the truth."
Gem, 12, Staffs, England
"I haven't read this yet, as I think that young people like Leona shouldn't actually write an autobiography. She has so much more of her life ahead of her yet! I like Leona, sure, but maybe she should stick to singing, not writing books!"
Jamie, 10, Bristol, England
"This book was AMAZING. It was so inspiring to hear her story. Leona is definitely the best singer ever."
Allie, 11, Bristol, England
"Wow!! I read it in a few hours, I couldn't put it down!! The pictures paint a thousand words."
Emily, 12, Lancaster, England
"I really liked her book because I didn't realise how much she cared for music, although I would have liked to have seen more about her life. I found the pictures interesting and nice to look at, but after a while I got a bit bored and wished she'd written more and put less pictures in. Overall, a FAB book!"
Alice, 12, Northampton, England
"I like Leona and I like her singing but I don't like her book because I got really bored! Just because my name is Leona, it does not mean I like Leona Lewis and I sent the book back!"
Leona, 8, Leeds, England
"I love Leona Lewis, she is my role model and when I grow up I want to be like her. SHE RULES!!"

Elle, 11, Newcastle, England
