I read half of Celine (I think if you're going to write a review you have to have read a substantial amount of a book), and I can't finish it. It just isn't for me. Heller is trying too hard to be cutesy, and I'm not enjoying the authorial voice commenting on everything. I've just got to a section where Celine (a 65ish PI) comes across a girl crying on a bench. 'Break-up?' Celine says, and then sits beside her and gives her all sorts of folksy wisdom which the girl laps up. I think Heller knows exactly what he's doing - he has set out to write this kind of book and he's achieving it well, it's just not the kind of book I like to read.
