Dig and Nadine have been the best of friends since school. They bonded through their love of music and kites, and even now they're in their thirties they spend all their time together. Unfortunately, Dig and Nadine are very very stupid and spend pretty much the whole book ignoring what everyone else seems to recognise. They are perfect for each other.
When Dig wakes up at thirty to realise that the young woman he slept with on the night of his birthday was only seventeen, it's hard not to feel a little grossed out. There is nothing more concerning than someone getting intimate with a person they are not far off having been able to be the parent of. Nadine is not much better. She breaks up with her boyfriend because he makes her a cup of tea in a horrible mug. If she hates them so much, why not get rid of them?
Anyway, having made some weird friend pact they then manage to fall out with each other over stupid things. This is made worse by the arrival of Dig's ex-girlfriend who broke his heart when she dumped him at eighteen. Nadine sees this as an opportunity to make contact with her old boyfriend who spins her a dreadful sob story and then ends up squatting in her flat.
This is one of those books that you are best not trying to think rationally about what happens, since so much of the drama could have been avoided if the characters simply spoke to one another. The scrapes that result after these bizarre situations are increasingly odd...and at times I wonder if I am on another planet as the actions of the characters make no sense. However, the kind of car crash that unfolded in front of us was - through the realms of detached reader - quite entertaining.
