Hannah and her new step-sister are total opposites. Hannah is a swimmer and loves the water. Katie can't swim and plays softball.  When Hannah is invited to her best friend Jacob's lake house she is excited. She and Jacob have been best friends since they were very young. She had heard so much about their lake house. Hannah had not planned on her new step-sister tagging along. On the way down to where they will meet Jacob, Hannah realizes there is something between Jacob and Katie. It isn't bad enough she has to spend the weekend with her step-sister there. She learn there are no parents and Jacob has invited two other friends.

Strange things happen. Hannah is racing Jacob when she is suddenly pulled under water. Later she sees something she identifies as a monster. The new friend Colin seems attracted to her. He is the one who tells the story of the drownings in the lake. When Hannah, Katie and Jacob visit the burned island across the lake Hannah finds a box with a diary. It is the diary of a girl who has gone missing.  Was she a victim of the lake? Hannah and Katie watch as their new friend Alessandra is pulled under the water. She surfaces and screams for help before she disappears.  All Hannah and Katie want is off the island.

This was definitely a very creepy, edge of your seat book. I read it in a little over two hours. I have spent a lot of time talking about it to my students. That is how good this book is. Now I must read the other book "What Waits in the Woods". I am sure it will be just as good.
