I was pleasantly surprised by this one. I can understand non-monogomy from an outsider's point of view. I've known people who were in open relationships and I intellectually know it genuinely works for some even if it's not for me. I get it. That said, I didn't know how comfortable I would be reading about non-monogomy with Jo as one of the main characters of said relationship. Getting to know her (and be in her head) in book 3 of this series, I couldn't wrap my own head around how she would move from an insecure woman with major body issues into a self-assured woman who was comfortable in an open relationship. I wasn't sure I could be convinced of the sincerity of such a premise. All I know is that after reading this, I should really remember that Harper Bliss never fails to surprise me. Her books have handle so many subjects (depression, body issues, alcoholism, infidelity, on and on and on) with such care, and so much thought, that I really shouldn't have felt trepidation in regards to how she would handle an open relationship, either. This was written from Caitlin's first person POV, though, and I really would have liked a glimpse into Jo's thoughts, too, since she's the one we've spent more time with over the course of the Pink Bean series. While this isn't my favorite Bliss book, I'd still recommend it.
