Having graduated college at 18, Sebastian Grant has continued to leverage his intelligence and determination to become a pediatric heart surgeon. The more accolades he receives, the more he's driven to pursue. Then he meets high school math teacher Leah Montgomery, and his fast-spinning world comes to a sudden stop.

Solving advanced math equations by the age of five, Leah has always wanted to pursue a PhD in mathematics. She willingly put that dream on hold to raise her brother. Now that he is of age, she's set on avoiding any obstacles to her goal--including romance.

When Leah receives surprising news in the process of taking a test for tracking her ancestry, she asks Sebastian to help her comb through aged hospital records to learn more. Soon his presence isn't so easily ignored. But when Sebastian learns his best friend also has feelings for Leah, he begins to question his resolve to win her. Attaining their deepest desires may require more sacrifices than they ever imagined.
