I am reviewing this book after having read Cheryl's autobiography which was published in 2012. I don't usually enjoy biographies, especially those written by authors with no interest in the subject, just the money that can be made from the book.
Sean Smith however doesn't fall into this category and instead writes books about subjects he is interested in and the research that goes into his work is fantastic (see his Britney biography). This is evident in just how much of what he writes here was similar to what Cheryl wrote in her book. He wasn't far wrong with most of what he wrote.
I intend to read more of Smith's biographies because of the research that went into them meaning you know that it will be a good read.
