This was cute! Like, giggle and swing your feet saccharine cute! I've only read one other book by these authors, but I did find that I liked The Soulmate Equation much better, especially in the delivery and the content of the story itself. It was a really interesting spin on the idea of soulmates being scientifically explained through the use of DNA and compatibility matching. I was pretty skeptical about the science being a gimmick to explain away the relationship between the two characters, but the story did end up unfolding in a way that I was satisfied with the conflict resolution at the end. Also, the characters were great. And hot damn, River scienced and mathed so hard I practically melted from time to time.

River and Jess, despite--or because of--their compatibility score, had really good chemistry, and I loved how organic their relationship developed after the compatibility reveal. I think my only quibble about them was that I felt a lot of their interactions were performative in public. It mostly isn't, because they acted the same way around each other when they were alone or with just family, but the whole publicity aspect--and the money incentive--did kind of muddle the surface for me a bit. Overall, though, I'm just really glad that the two of them found a way to make it work. I'm all for the HEA initiative in romances, and the end to this had me closing the book smiling to myself for the longest time!

Also, Felicity Chen is a national treasure, and quite possibly my favorite aspect of this book. I said what I said!
