I bought this book only because it was in the 3 for 2 sale at Waterstones, never having heard of it, or the author, before. Reading it got slightly uncomfortable at points - for one, the moral dilemma at the crux of the plot had me squirming because it's one of those situations you just don't wanna think about - secondly, characters take it in turn to narrate chapters, and though this generally works well, the fact they all use the same introspective reflective tone can get a bit eerie.
One review inside the cover says the book ends with a big twist, so I started trying to spot it from the start - no chance, it came totally out of nowhere. And when it finally turned up, it had me bawling my eyes out (I haven't cried at a book since I read "The Last Battle" (Chronicles of Narnia) at the age of about 8). Seriously, I cried for about 10 minutes, and I don't even have kids.
At the same time, the book isn't an emotional blackmail attempt using cliches as tear-jerkers, but simply, gently and originally written. It comments in a roundabout way on families, parenting, and growing up. I'm tempted to get hold of some more of the author's work, but I'm worried it won't live up to this one.
