I was introduced to the writing of T.M. Logan through her book The Holiday, and her new book sounds just as good as this one. Novels set on a trains are always exciting, and the mysterious circumstances surrounding this story and the baby passed over to Ellen in split second that changes everyone's life adds a strong sense of mystery and intrigue into a normal, everyday situation. I'd love to find out what happens in the rest of the story: why has Mia's mother abandoned her? Why has she picked Ellen? What will happen in the rest of the book?
