Jess Davis is a struggling statistician, a mom, and very single. When she hears about GeneticAlly, a matchmaking company that can find your soulmate through DNA testing, Jess is curious about the numbers but doubtful she'll find someone. Things change when she gets an unheard-of 98% match with GeneticAlly's founder, Dr. River Peña. While apprehensive about the results, Jess gets an offer impossible to turn down, fake dating with a payment. Already scrambling to make ends meet, Jess reluctantly accepts the proposition while learning more about the science behind a soulmate and the scientist behind the algorithm.

The Soulmate Equation is a cute romance with a sci-fi spin. The science is easy to understand, so that shouldn't dissuade anyone from reading it if romcoms are your jam. I enjoyed the book, the friendship between Jess and Fizz, the familial love in the Davis family, and Jess' character development in coping with her mom's abandonment. On the other hand, River is an underdeveloped character whose personality is just "being a scientist". Even his sisters are more interesting! Because of this, the chemistry between Jess and River is inorganic, and frankly, it feels like they're still fake dating towards the end. For avid romance readers, The Soulmate Equation could be a refreshing read. But for someone who doesn't read many love stories (me), this is a solid three stars.
