This book is about a man with a disability, who has a daughter with the same disability, and the man wants to show his daughter that the disability does not prevent him from achieving anything he wants to do in life. Consequently he makes up a list of 50 things to do in his 49th year, and the book basically goes through this list, whilst also touching a little on his childhood growing up with a disability.
The book is relatively interesting, but it really is an extension of a list at the end of the day. He does many things, but doesn't go into any real detail to whet the reader's appetite or make them envision doing the things themselves. For example, the main character goes scuba diving. I have never been scuba diving and he could have gone to great lengths describing it but instead he brushed over it really, explained that the sea was cloudy, he couldn't get to the sea bed, and it was a little disappointing. Very brief description.
At the end of the day Holland wrote the book because it was an item on the 50 list (write a book and get it published), not because he has any writing skill or because he wants to be an author. And I think this is evident in his writing. I would say don't give up the day job, but he never intended to so it would be a waste of breath.
I wouldn't recommend the book. I wouldn't read it again. In the unlikely event that Holland writes another, I think I would graciously pass on the opportunity to read it. I would however note that grammatically there are only a couple of mistakes. So the proof reader is a good'un.
Therefore I give this book a 2 out of 5 rating.
