The bestselling author of Windfall and The Statistical Probability of Love at First Sight returns with a meet-cute romance about Hugo and Mae, two teens who are thrown together on a cross-country train trip that will teach them about love, each other, and the futures they can bui...ld for themselves. Having just been dumped by his girlfriend, British-born Hugo is still determined to take his last-hurrah-before-college train trip across the United States. One snag: the companion ticket is already booked under the name of his ex, Margaret Campbell. Nontransferable, no exceptions. Enter the new Margaret C. (Mae for short), an aspiring filmmaker with big dreams. After finding Hugo's spare ticket offer online, she's convinced it's the perfect opportunity to expand her horizons. When the two meet, the attraction is undeniable, and both find more than they bargained for. As Mae pushes Hugo to explore his dreams for his future, he'll encourage her to channel a new, vulnerable side of her art. But when life off the train threatens the bubble they've created for themselves, will they manage to keep their love on track?
