This book gave me Beth O Leary Flatshare vibes - two people, haven’t ever met but have this special connection with each other that intensifies the story. I really loved the characters in this novel: particularly Daniel. I thought his character was so amazing and I kind of felt that the focus was more on him than on Nadia which I liked because I think a lot of books nowadays are usually about the woman falling in love so it was good to see the guy do it. I thought the whole concept of the tube and commuting was a really nice touch - kind of makes you think that if that ever happened to you - how would you react? But then again, I feel like the characters Nadia and Daniel had such a varied reaction to this journey that they’d embarked on and it really did it justice. I think this was really well-written, it kept me reading because I just couldn’t put it down!
