Christina Lauren knocks it out of the park again! This writing duo just know how to write a fluffy little romance. Now, this is not my favorite novel of theirs, however I think it was their most emotionally interesting (that I've read so far). The family connections were written so well, and the stakes of this relationship were high due to there being a child involved. I'm not usually a fan of children in romance books, but LOVED Juno in this. The chemistry between Jess and River was emaculate and River and Junos relationship was beautiful (the epilogue had me crying 😭). 

I think the thing that makes this book not 5 ⭐ for me is the over explaination of the scientific aspect. Once the plot twist/third act conflict begun I was getting a bit overwhelmed with all the science explaining. 

Great read! You always know what you're going to get with these authors and I honestly appreciate that.
