 This one is hard to rate. This was a love/hate relationship, in every sense of the term. There were parts I loved and parts I didn't love. The h/hr start off hating each other with a hero who started off on the wrong foot for me with his abrasive assholery behavior. But Yates did a pretty decent job bringing me around to warming up to this guy with some development (very slow at first), apologies and a tear-jerking backstory. This definitely wasn't perfect, in fact I felt Yates focused on the wrong part of the couple's relationship through most of the book. (view spoiler)[I mean if you are going to write an unexpected pregnancy after a ONS as the central focus, see it through to the end, not just the early stage of the pregnancy. (hide spoiler)]. This was all strained tension and awkwardness, not enough fun & play to balance it out IMO. Because of that, this felt like a novella. The pacing and fallout of the drama felt very hurried and rushed. Not enough time was focused on Sierra and Ace getting to really know each other and open up. That kind of all happened a little late. And the 'big fallout' was over a silly simple picnic with a very rushed reconciliation over a day. Too rushed and too fast. 
 Sierra and Ace's chemistry was fire and sexy...it just took a while. I wasn't sure about these two with the way they started off. But the chemistry is there and it definitely helped seeing our cynical jaded hero so desperate to keep the girl and really wanting their baby. Seeing prickly world-weary Ace be humbled and captivated by Sierra who is in many ways naive and sheltered but has fire and sass to match his was great to see. I just wanted to see more of it. The epilogue was adorable but again....that should have played out more in the story itself. (view spoiler)[At least after the baby is born. Readers needed to see these two really settle into a committed relationship and dealing with the different stages of the pregnancy. I really wanted to see that. (hide spoiler)] 
 But all in all, I'm a huge Maisey Yates fan. While this one wasn't her best work and not my personal fav, it was still pretty enjoyable for me. I can't recommend this author enough. Her writing is definitely special and different. I always find her books so fun and her writing so refreshing and engaging. It's smart, sharp, witty and sexy. This one isn't as funny as the other Cooper Ridge books but it had it's moments. It was especially good to see Jack and Katie in here. And I will definitely be continuing this Cooper Ridge series, I'm enjoying it so much. I can see Yates is branching this series out into sub series and I think that's a really smart move. A lot of fun interesting characters with a lot of grit.
