First things first - this book isn't a sequel to We Need to Talk About Kevin. A fairly obvious point to make, but one that really does need making. Because this seems to be the expectation of many reviews that I have read. Certainly, Kevin is an amazing and poignant book, and if you haven't read it yet, then where the hell have you been? However, as a writer, Shriver has the ability to write about a wide and varied range of subject matter. This is what good writers do. If you really want to learn more on high school massacres, then rent out Bowling for Columbine.
So, if you can get Kevin out of your head for five minutes, then please turn your attention to The Post-birthday World. And this is one novel that really is deserving of your attention. In the first chapter, Irina is faced with a life changing choice: does she stick with her decent, reliable yet slightly dull long-term partner Lawrence, or does she give it all up for a life of passion and unpredictability with hard living and exciting snooker player Ramsey? The book then branches into two; in alternate chapters it shows what happens when Irina leaves Lawrence, and what happens when she stays.
The result is an entrancing read. Now, I'll be the first to admit that snooker is not the sexiest of sports. But, as with Shriver's other sports novel Double Fault, it's almost not what Shriver writes about but the way she writes about it. On paper, her subject content sounds fairly dull; snooker, middle age people falling in love, the politics of Northern Ireland. And yet she still manages to intrigue and draw the reader in, and to make them care. Plus, anyone who is able to take the dull relation of the sports world and make it sound interesting and even a little bit sexy will always get my admiration.
The Post-birthday World is also a brilliant observation on the nature of relationships and love. Are we ever really happy with what we've got; should we choose to stick or should we twist and gamble it all for something greater? And in the end, are we left with the same result anyway?
Unlike Kevin, this book won't make you gasp at the end, and it won't make you shocked or horrified. But it might make you think, and change how you look at the world just a little. Which is as good a result as any.
