I liked the characters and the plot was fine, but it irked me a few times.
Miri was a curvy woman that was bullied for most of her life by her mother and boyfriends for her weight. As a fattie myself I could relate, it was nice to see that she took some care of her health, the yoga and mentions of how much water she was drinking were good, but even as a fat person it was hard to read how much sugar she was eating. I don't care how people look, but eating baked goods all the time is just unhealthy, and she was rarely mentioned eating something different. I got it that she didn't want to change, but it seemed like it was such a hardship for her to eat something healthier and it made me roll my eyes. I love baked goods like everyone else, but I wouldn't be able to stomach cakes, muffins and cookies all day, every day. Oh, sorry, she liked yogurt too ;) Her thoughts when she saw Kaz eating apple slices were weird, banana bread was fine for her, but fresh, healthy apples were only for the health nut. Btw, Kaz was eating carbs only on his cheat days, apples are healthy, but it's fruit, sooo carbs ;)
The plot was kinda predictable, yet still I was disappointed. I hoped it would be different from the first book, but nope, third act breakup (yeah, it wasn't a real breakup, but still...)! The only surprise was that it wasn't Nico who fucked up. It was a little weird how easily he got over his jealousy and discomfort in the poly relationship.
I liked the guys for the most part (Nico and Kaz pissed me off a bit). Duke was my favorite, the guy was a hulking teddy bear that turned into a kinky demon in bed ;) Ace was a chaos personified, but he was cute too.
