As an author, I do enjoy positive feedback on my work. There have been some nice reviews of my books in the media over the years, but what always means most is when an everyday reader gets in touch to say how much they’ve enjoyed one of my books.

The book I have had the most reader feedback on is my biography of Justin Bieber, which is now a global bestseller. I awake each morning to another round of Tweets, Facebook messages and emails from Bieber fans around the world who have read my book. They are  friendly and positive, and often very sweet.

The best of all came from a mother who wrote to tell me that my Bieber book has got her daughter back into reading and schoolwork again. That was great to hear. Yesterday, this card and teddy bear arrived in the post from the girl. It really made my day life.
