Michelle Mason comes out of a coma 18 months after experiencing a deadly car crash. She still must go through a lot of rehabilitation to try to regain her overall strength as well as the use of one of her arms that was injured in the crash. In addition to her physical issues, she seems to have no memory of the accident. This is a real problem because a young man, Noah Butler, was killed in the crash. No one knows why he was even with her in the car. On top of that, now that she's come out of the coma, there's a lawsuit waiting for her.

The day her husband brings her home from the hospital, there's a small gathering of friends waiting at her house along with her son, Tyler. They have cake and champagne and present her with a little welcome home party. Everyone seems to be acting a bit oddly, though, and Michelle can't really figure out why.

After a rather awkward intimate reunion with Drew, her husband, that night, she sleeps late the next day. When she does get up, she finds that her daughter, Nikki, still isn't home. That's when Drew is forced to admit that Nikki ran away months ago and that he has no idea where she is. Not only that, Drew has relocated to New York part time to work and is going to leave the next day to return there.

Michelle feels as if everyone around her has lost their minds as she weaves her way through one undisclosed secret after another. One thing she knows is that she's going to find her daughter if it's the last thing she does. Others may have just decided to let this be, but Michelle won't. Nikki is her daughter and there's nothing that a mother won't do to protect her child.

WHAT A MOTHER KNOWS is actually an excellent book. It draws you in and holds you there while Michelle hunts for her daughter as well as tries to figure out what others are keeping from her, and there's a lot that's being kept from Michelle. The plot is engrossing and makes you feel as if you have no choice but to see it through to the end.

There's even a huge twist at the end that will stun you. Now, having said that, I found it very hard to like most of the characters in WHAT A MOTHER KNOWS. This doesn't take away from the book, but it did make me rather annoyed while I was reading it. There's probably one truly likeable character in this book and that's Tyler, Michelle's son. I ended up feeling very badly for him. Her friends are part time friends, at best, and don't even get me started on her husband! I was thinking the whole time I was reading that I would not want to have Drew for a husband if I was recovering from an accident that nearly killed me. What kind of a man brings his wife home from the hospital and then takes off a mere 48 hours later to leave her on her own while he jets across the country for 2 weeks to work?

In the end, WHAT A MOTHER KNOWS is definitely worth your time. This is a puzzle that you won't walk away from until you've put that last piece in place.
