I had to read this story several times in order to really appreciate it. But somehow it gradually got under my skin, and even now - though I know it has a happy ending - reading the part with the break-up makes my gut clench. Impressive in all its understated, tense, realistic romance.
In addition, the idea that Marcus calls 'his biggest lie' is actually one of the things I respect about him. Even if in the end he does become a threat to Trevor's marriage, he didn't set out to do this. And so I feel that he is being too harsh in judging himself, even if I can understand why he feels bad about the affair.
