When I ordered this from Amazon, I was so excited. I couldn't wait.

When it did come, I was immediately disappointed. Nowhere did it say on the description that the writing was huge, so aimed at a younger audience. Nowhere did it say that a quarter of the book was snippets from Jacqueline's other books, and a quiz that had been repeated hundreds of times in all Jacky's other books.

I love Jacky's plots and the way she engages the reader, but in this book, it was just like any other of her other books. It was an obvious plot – 2 sisters. Opposites. Don't get on. One gets ill. Get on again. A lot of plots used by authors are obvious but made unique, but to be honest nothing was unique about this book.

I enjoyed it as a light read, but it took me half an hour. I probably didn't enjoy it because I'm 12 and have read every single one of Jacky's books. I knew what to expect, and maybe I'm too young for her books now. Maybe an 8-year-old would enjoy this more than I did, I just found it very easy, with no twists or turns or unexpected events in the plot line.

Talking about the characters, I think this could have made the book more interesting, had they been original. A character can easily transform a book that is boring – but this made no difference to this book. The characters I found very repetitive and unoriginal – Melissa (obvious girly name) – prissy, girly, pink. Marty (obvious tomboy name ) – arty, boyish, funny.

What would have perhaps enhanced this book is if the chapters were told by different narrators, perhaps by Melissa and Marty. I found Marty's narrative voice annoying, because it was always from her point of view. I know that the silly arguments they have were not always Melissa's fault, and should have been told by her as well.

As for the trailer, I think its even worse than the book. It publically advertises sisters hurting one another – the trailer shows the two girls fighting and being aggressive towards one another. Even if this was in the book (which it isn't – they don't physically hurt each other), its inappropriate for a trailer that will be publicly viewed by millions of girls, who probably have siblings.

Overall, I found the book dull, lifeless and the plot boring which is disappointing as I have loved all of Jacky's other books. However, my opinion may be because of my age, so I would love to hear what other people think of it.
