Query: story dragged on for too long

The core of this book is a love story, surrounded by a passenger cast on a cross continental Amtrak train. Overall the novel is a disappointment. Basically the first two thirds of the book was a painful read. It drags on and on with dull and what-is-the-point subplots that prompted me to give up reading several times. But I managed to endure until the part where the train was hit by the avalanche. So it finally got to the climax of the story and it gave me a reason to keep going. The union of Tom and Eleanor is sweet, though the love story itself is so contrived and unreal. 2 stars for adding some twists at the last couple chapters of the book.
