Thank you to Forever Grand Central Publishing and NetGalley for providing me with a copy of this title to read and give my honest review. The opinions expressed here are my own.
I will say I honestly did not enjoy the first book in this series. I didn't even finish it. I am blaming that on how it was presented but also the fact that I listened to it on audio and really didn't like the narrators. But I wanted to give this author another chance and went in with zero expectations of what I would find. I'm glad I gave it a go. This presentation was much better than her first. My search for F1 books that truly present the sport in an easy and believable fashion has been wanting. Add in romance and there's the potential for disaster if it's not done right.
Things I enjoyed in this book:
The age-gap romance. While there was a gap, I didn't feel like it was so big the characters seemed like they would never truly be together. Both characters were mature enough to know what they wanted from life and where they wanted their lives to go.
The fast but slow burn romance. Since it starts with a bang and then falls back, I needed to watch that burn and love it. I did. There was chemistry, yes, but also a connection between the characters that was palpable.
The emotional turmoil of the characters seemed on point. I felt it to my bones when they suffered and when they felt joy. 
The pacing was good. I never felt like it stalled or like there were times I didn't want to continue reading. As a matter of fact, I read this title in a very short time.
Dual POV. I was happy with how it was presented. I love being in an MMCs head almost as much as an FMCs head. It was nice to have Klaus showing us who he was rather than just seeing it through Natalia's eyes.
What I didn't like:
Surprise pregnancy. Ok, I won't say I didn't like it totally. I knew it was coming. It was very obvious with how the author set up the relationship and with the conversations that were being had, I just didn't totally believe the things that happened when it was revealed.
The ending. It just kind of ends? There's no epilogue, no nothing. I feel like I was left wanting more. Wanting to know if there was a happily ever after. Wanting to know where their lives took them given their circumstances.
While there is mention of the characters from the first book, and things that happened that were important (yes I read enough of the first book to know things that were important), they are not built upon in any appropriate manner. The author assumes you've read the first book and know what happened. I needed more flashbacks so the story made sense. This elimination left plot holes. There's  a ton of overlap between book 1 and 2 and it seemed the author did not care to share why it was important. 
Given the characters ages, I felt like there was more drama than was necessary. For adults in their 30s and 40s, it was more like teen or young adult angst. I just didn't believe in it as much as I would have liked.
Would I recommend this book? I sure would, but only if you've read the first one so you have the background. And I recommend reading them one after the other, so the plot is not confusing or forgotten. Juniper does a better job with the F1 in this book, as well. In the first book, I felt like she shoved a lot of technical information at the reader. For someone who doesn't follow the sport, it was hard to absorb. This book was much lighter on that and easier to understand.
3.5 rounded to 4
