The Christmas train by David Baldacci

In David Baldacci's novel The Christmas Train, a journalist named Tom Langdon embarks on a cross-country rail journey to Los Angeles after being banned from flying. Along the way, he unexpectedly reunites with Eleanor Carter, a former lover and fellow reporter whose departure years earlier remains his greatest regret. The train becomes a microcosm of life, filled with eccentric characters like the mysterious Agnes Joe and a director named Max Powers, who is secretly orchestrating events to inspire a screenplay. As the passengers face a perilous blizzard and an avalanche in the Rocky Mountains, the forced confinement compels Tom and Eleanor to confront their shared history. Amidst holiday celebrations and unexpected danger, the narrative explores themes of second chances and the transformative power of the journey itself. Ultimately, the mechanical and emotional delays serve as a catalyst for Tom to resolve his past and find a new future with Eleanor.
