Once upon a time, as all good stories with happy endings begin, a penniless young mother walked the streets of Edinburgh with her beloved baby daughter, hoping to make her fortune. In truth, "fortune" is probably over-exaggerating; enough money to feed and clothe the two of them and put a decent roof over their heads was all this young mother asked, but it was proving to be incredibly difficult.

Yet this is no fairy tale from the Brothers Grimm or Hans Christian Anderson, it's the true story of one of the most successful women the world has ever known, who in 1990 came up with the idea for a book about an orphaned boy wizard. The boy's name was Harry Potter, the young woman, JK Rowling, and the rest is history!
