He walked away from the love of his life, but when fate reunites them, will it lead to a new beginning or a final goodbye?

When River Jung, an ambitious freshman from Korea, steps onto Harvard's leaf-strewn campus in the fall of 1990, love is the last thing on his mind-until he meets Deborah Noe, a vivacious aspiring doctor. Their connection is immediate and undeniable, blossoming into an all-consuming romance that reshapes the contours of their lives. But just as their dreams begin to take shape, a family tragedy forces River to return to Korea, leaving Deborah behind and shattering their shared plans.

Years later, River returns to the US with his heart still tethered to Deborah, longing for a second chance. He channels his heartbreak into building Charis, a tech start-up aimed at eradicating loneliness. Meanwhile, Deborah builds a career as a psychiatrist, using her own experiences to help others heal. Though their lives have moved in different directions, fate draws them back into each other's orbit time and again, reigniting old questions about love, loss, and the roads not taken. As they navigate the distance between who they once were and who they have become, they must decide whether their story has truly ended-or if a new chapter is waiting to be written.

Set against the backdrop of Silicon Valley's unforgiving environment-from the dot-com bubble bust to the subprime financial crisis-WHEN RIVER LOVES DEBORAH is a novel about the architecture of connection. It reveals how love defies conventional boundaries and how our most profound relationships take shape in the spaces between possibility and unpredictability. It's a story that asks: What survives when geography, time, and circumstance conspire to separate two people?

The story spans decades of missed connections and chance encounters, comparable to the relationship between Sam and Sadie in Gabrielle Zevin's TOMORROW, AND TOMORROW, AND TOMORROW. It also draws inspiration from the rich character development of Ann Patchett's TOM LAKE and the tender nostalgia of the movie PAST LIVES.
