The New York Times Bestseller and A Reese's Book Club Pick "This love story between Lucy and Gabe spans decades and continents as two star-crossed lovers try to return to each other…Will they ever meet again? This book kept me up at night, turning the pages to find out, and the ending did not disappoint."-Reese Witherspoon "One Day meets Me Before You meets your weekender bag."-The Skimm "Extraordinary."-Emily Giffin He was the first person to inspire her, to move her, to truly understand her. Was he meant to be the last? Lucy is faced with a life-altering choice. But before she can make her decision, she must start her story-their story-at the very beginning. Lucy and Gabe meet as seniors at Columbia University on a day that changes both of their lives forever. Together, they decide they want their lives to mean something, to matter. When they meet again a year later, it seems fated-perhaps they'll find life's meaning in each other. But then Gabe becomes a photojournalist assigned to the Middle East and Lucy pursues a career in New York. What follows is a thirteen-year journey of dreams, desires, jealousies, betrayals, and, ultimately, of love.
