I can't decide if it's a 3 or a 4 star so I'm going in the middle with 3.5.
First, I loved, loved, the banter. Easily 5 stars for banter alone! I think they had great chemistry and loved their jokes. I thought it was strange that she had never interacted with her best friend's brother, especially since the brothers were close. It's not like they were estranged or anything. Did she never see him in Micha's photos or during a FaceTime? Doesn't that seem strange to you? It's not like he just moved back to the city, he's been there the whole time. And not once did he join them for activities like dinner or drinks???
While this started out strong, it did sort of lose me as the story progressed. I didn't like their forced arguments. They were too much and too over the top. I know they had to sell it but I hate that they didn't think about the other couples who were truly there to get counseling.
Speaking of the counseling retreat, that thing costs $15,000 for an 8 day session! And it's weird that it was just her coworkers there rather than other people. But also she called at someone having the ability to pay for the retreat... but at the same time, all of her coworkers could easily afford it every single year! But really, what even was the $15,000 paying for??
You can't tell by the beginning or the cover, but it does get kinda raunchy/spicy about halfway through and keeps that up. I had to skip quite a bit. Normally, I don't mind if I know that's the kind of book I'm getting myself into - how much to read and how much to skip, but I wasn't expecting it.
I liked the ending and thought it ended on a good note. I enjoyed it and would read more by the author.
