I felt compelled to write a review of this book after reading the ones already submitted below. I know that enjoyment of a book is personal to the reader, but I was surprised to find that there were so few positive reviews. The Child In Time is one of my favourite books of all time and certainly my favourite of the novels by McEwan that I have read. I disagree with the opinions that only parents, couples and politicians will enjoy or get anything from this book - I first read it for my A Level in English Literature (i.e. as a 17 year old student) and loved it, and have since re-read it at age 25 and loved it even more because now I'm older - albeit still childless and still not a politician - I have been able to gain more meaning from it and discover new levels to it.
For me, the best thing about this book is the quality of the writing. I find when reading The Child In Time that I can visualise perfectly the scenes and empathise with the feelings McEwan describes, despite having never experienced the trauma of losing a child, the break-up of my marriage or witnessing a friend's mental breakdown. That to me is the mark of a top-class writer. I felt that the characters were utterly believable, and although the plot may not be action-packed from start to finish I liked that about it because somehow that makes it more starkly realistic.
Anyway, as I said at the beginning of this review, I know everyone who reads The Child In Time will feel differently about it, and just because I love it doesn't mean you will. The reviews below just seem overall to be negative about this book and I wanted to speak out in favour of a book that I feel is beautifully written and ultimately uplifting.
