Morgan Kincaid is standing on the platform waiting for the train after work when a stranger comes up calls her by name and hands her her baby. Then the woman jumps in front of the oncoming train. The story is told in alternating parts between Morgan trying to find out why this stranger would do something like this, and the events in Nicole's life that led up to that moment. I could not put this book down. This is the best kind of suspense book.... great plot twists and a compelling storyline. I highly recommend it!
