He can solve the mysteries of the universe, but can he unlock the secrets of her heart?

As a celebrated astronaut, I've unraveled the enigmas of the cosmos. But the puzzle of what makes relationships work? That's always eluded me. I'm more comfortable studying life's building blocks than navigating the perplexing world of human emotions. After a scandal at my job, I return to my small hometown a disgraced outcast. But then I meet Abigail Baker.

My captivating new neighbor is everything I'm not - warm, emotionally attuned, and able to charm an entire town with her vibrant spirit. With her quick wit and generous heart, she sees right through my gruff exterior to the wounded man beneath. The more time we spend together, the more I begin to hope that maybe I'm not a lost cause.

But I've never been good at love, and when ghosts from my past threaten our budding connection, I'll have to prove to Abigail, and myself, that I'm willing to change and open my heart. Is it too late for this science nerd to learn the equations of love and become the partner she deserves? When forces conspire to separate us, I'll have to take a giant leap of faith to fight for a future firmly on the ground, by Abigail's side.
