Learning to Swim

This was an interesting book about a woman who is on a ferry goign to visit her boyfriend and out of the corner of her eye sees something being tossed off of a passing ferry in the opposite direction. Without giving it much thought she believes it was a child and she dives into the water. After managing to swim the child ashore in freezing temps and keeping it alive she realizes that no commotion has been made about this missing kid and that there is the potential that someone purposely tried to drown a little boy. Fast forward and she has met with the father and found out that his wife and kid disappeared 6 months ago and due to ransom demands he couldn't go to the police, blah blah blah.
The good part about the story is that the kid ends up happy but the surprise outcome of the book was expected and overall the story line is just one that's been done many many times I feel. I did enjoy the read though.
