This book was nothing like what I expected. In fact, I'm still a little confused by it and have had a hard time sorting out my feelings. Mr. Johnson dies and then begins living his life backwards. This is where the confusion sets in. People are talking forward but Mr. Johnson is hearing backwards. This and all of the other backward things made my head hurt.
What did come across very well is Mr. Johnson's loneliness. It's heartbreaking, so the reader is happy when he meets Miranda, who is also living her life backwards. From there on, well there's only one way it can end, isn't there? Or is there another way out? You'll have to read it and see for yourself.
This tale requires some thought from the reader, while at the same time demanding that the reader not put too much thought into certain aspects. If that sounds intriguing to you, give it a shot, you'll probably enjoy it!
