I was slightly confused by the writing style when I started reading this (probably doesn't help that I was jet-lagged, sick and struggling to keep my eyes open - so I'd take this review with a grain of salt!) and wasn't sure what Winman was trying to achieve.
By the time I hit the halfway mark I was in deep. The second half of the book made so much more sense to me and I finally understood. (Perhaps my jet-lag had worn off...)
I can appreciate why others have loved it so much, it pulls at the heart strings. It's sensitive yet powerful; delightful yet fragile and heartwarming yet heartbreaking.
