Matt Haig: The Midnight Train, Canongate, ebook available 

Midnight Library is a book I still buy as a gift or recommend, a wise fable with much food for thought. 

"Midnight train" continues with this train of thought: what happens if you were given a second chance and are on a train  stopping at important pathways of your life, this after you died and became a ghost, as happens to Wilbur, a bookseller who started a successful book chain but lost the love of his life, Maggie, during the process. 

For me I guess the surprise element was lacking with Midnight Train and although still filled with some insightful thoughts, didn't  quite do it for me this time.
