This was an okay read, but I didn't connect with either of the characters very well.
My only emotional response here was from the death of the dog Harry. And, as the owner of a ten year old lab with arthritis, I think most of that was projection.
I actually liked the ex-wife character. She redeemed herself from the classic evil-bitch-syndrome that so many women in m/m fiction suffer from, which made a nice change.
