The premise of this book had me hooked. I commute every day and see the same faces all wrapped up in their own worlds, God forbid anyone talking to each other! This is a classic boy sees girl, sends girl cryptic message via paper, and so on. We have them missing each other in person, each not knowing that the person they were supposed to meet was the person from the train. Life gets in the way, but maybe karma is waiting for right place right time? Daniel and Nadia are meant to be, but fate sends them around and around while we, the readers, get to know what they want from a partner, what they don't want, who their friends are and how our lives and actions impact others. I have to say that I was sorry to finish this book as I enjoyed it so much.
