This entire novel is a non-sequitur. Don't let the prologue suck you in, the rest doesn't make sense. A happy novel? Hardly. For the middle 3/4 it was predictably full of despair and the underlying anger was cliche. And the overall premise--that a perfect marriage can change so quickly--is ridiculous. Neither Rob nor Allison behaved close to what one might consider realistic. Evans sets them up as the ideal loving couple, but then shows them both to be selfish and egotistical. Ugly. There is no depth, just attempted manipulation of the reader's emotions. The irony is that it is not emotional because, knowing the formula, most of the novel was spent waiting for the obvious. I found myself skipping passages but didn't miss a beat.
