I have just finished reading this book, and felt compelled to write a review. As other reviewers have said, the title of the book doesn't do the book justice, and the depth of the book was an unexpected and pleasant surprise.
You get completely drawn into Jo and Dan's lives, the chapters where you read about Dan's childhood are shocking and emotional, and the one thing that struck me, was how accurately the writer could describe how a 6 year old would think and talk.
The writer is very witty and her sense of humour made me laugh out loud many times. The journey that Jo, her son Alfie, and Dan go through, will have you enthralled to the very end.
I would recommend this book to anyone, and I can't wait for her next book. By far this is the best book I have read in a long time, and I read a lot! I just could not put this book down.
