Honestly, I wasn't a huge fan of this book. It took me a while to figure out what the problem was, because it's not that Ahern can't write. The prologue is beautifully written and sets up an intriguing mystery. Who is this woman? How pregnant is she? Has she lost the baby? How did she fall down the stairs? Who was on the phone?
I couldn't wait to get into the book and find out what happened. And then - I just didn't believe it. And I'm not even talking about the plot, as implausible as it is. (Boy donates blood, girl gets boy's blood after falling down the stairs, girls suddenly has all of the dude's memories.) The problem was that I didn't believe the characters, at all. They didn't seem like real people, they seemed like devices to churn the plot.
I feel the need to give examples of what I mean, though they probably will seem petty. Joyce's dad is described as having planned his entire life out, yet when they're in London doesn't know how to pack a suitcase and makes a disaster of it. It seems like anyone who is all about organization should be able to fold his clothes and put them in a bag. Joyce, on the other hand, is described as just rushing into things in life without thinking them through - yet she's spent the past ten years redecorating her house in a loveless marriage. Really? So, she flies by the seat of her pants, but no affairs or other craziness outside of choosing drapes in all those years of boredom? Ooooooo-kay.
Other stupid things that annoyed me: Justin, the boy blood donor, makes a slightly cheeky remark at an elderly lady in the dentist waiting room. Her response is to throw a magazine at his head. Really? That's just not really something people do, and Justin appears unsurprised and just keeps walking away. Then, Joyce again. She miscarries in the middle of her second trimester, and in one scene there is very detailed description of her pulling on her jeans. So ... she's already back in pre-pregnancy jeans? And if so, she doesn't feel a pang or anything about that during the FIVE PAGES she's busy pulling them on?
I could go on, but I suspect I'm the only one who would be interested.
Other that all that crap, though, there are other really well-written pieces sprinkled throughout the novel. At one point Ahern describes staring into a mirror, how your face looks like a stranger's. (I never knew other people did that.) The grieving that Joyce does for her baby, including her wanting to just be alone and feel self-pity - that was great. (Not for Joyce, but you know what I mean.) And the way Joyce and her dad talk about slowing down and enjoying the present rang very true for me.
So, in summary, eh. It wasn't my favorite, and I wouldn't recommend it to most people I know - though I do know a few that would probably really like it.
