I'm just glad that the wife who's protective of her marriage managed to do so. This story is told mainly from two perspectives, Catherine Winthorpe and Neena Ryder (I mean Dr. Neena Ryder), and I pretty much skip over Neena's POV for the most part because she's such a cheater and ungrateful human being who's set out determinedly to rob and ruin other people's life when she already has an adoring and loving and accepting husband.

Catherine is an amazing protagonist.
Her method is questionable at times, but I just have to root for her.

This is a very satisfying read.
The fact that it's not too long is a big plus.
