For some reason I had forgotten I had already read this. And well, the title seemed applicable right now.
Well written. The ending is... not very obvious, but a little. Did I know this the first time I read it? Perhaps not. The small chapters in italics in between do give very clear hints as to what Jake and his girlfriend - the narrator - are up to. The discrepancies in the world are a bit too regular; they are not increasing in intensity and loose the effect after a while.
