I always had a problem with the prose in 'The Slap'. Something about it just didn't feel convincing. Scenes grated and dialogue sounded forced. That is not to say I didn't like the central conceit.
'Loaded' however is the real deal. It's brutal, fast-paced and, possibly due it being the somewhat-autobiographical first novel, genuine. It is important too for it's commentary on multicultural urban Australia and generational change. The fact that a lot of the back alley fucking is set/took place in my block in Brunswick added extra charm.
