Having read some of the weaker review scores, I was apprehensive about buying this book, but the topic and impressive list of cover reviews intrigued me.
My conclusion is that the book is a 'curate's egg'.
I failed to find anything remotely resembling genius in its covers, but there is certainly a fair smattering of original thought mixed with modified versions of old themes and ideas. If you are tolerant of the style of writing, I think the structure of 40 short imaginings (mostly 2-3 pages) makes an enjoyable excursion that one can dip into over the course of a few days to cover the entire material.
Whilst reading the text, I was conscious that the stories are the product of someone who has worked as a stand-up comedian, where brevity and punchlines are important.
Having now read the book, I do still find some of the cover reviews somewhat amazing, although I recognise that not all reviewers read a book they are asked to comment upon, nor are their clipped comments always reprensentative of all reviewers. After all, no author in their right mind is likely to agree to their publisher printing that the book is 'not worth reading.' Nevertheless, I'm afraid that I did not feel the book represents 'jaw-dropping quality of genius' (Observer) or that one 'will not read a more dazzling book this year' (Stephen Fry). However, is due to the author and publisher for rounding up such an impressive and positive range of reviews. After all, that is what these comments are there for: namely, to help sell the book.
On the positive side, I did enjoy many of the imaginings, both for their humour and in a few cases, their originality. If the book consisted of the 20 best stories, then I should have been more inclined to score it with 4 stars, but I felt that some of the stories were simply modifications of ideas that have been around in the philosophy, mysticism or science fiction literature for a long, long time.
Eagleman certainly applies his knowledge from psychology to capture and weave together the many mundane, the peculiar, the bizarre in our lives and reconstruct them in some amusing and on occasions highly original ways. For this he deserves credit. However, I should temper my expectations when purchasing this book, so as not to have a disappointing experience on reading its pages. Also, I am glad a read the book, since the few genuinely original ideas between its covers are a delight to encounter.
