This is a cute book.  The illustrations are great, and I love the graphic novel style pages! I also liked the way it simplified a business model for young people. Looking at target market, and how to make a profit. All of this was done very well and explained perfectly for a young person or someone new to business. 
However, being based in the UK I found it to be irrelevant in a lot of places. A lot of the terminology was US based, and therefore redundant when reading from a UK perspective. Lots of things were not relevant or understandable over here - some parts (ie cheques) felt a little old fashioned.

I liked the premise of this book, but don't think it work for UK readership.
