I have been trying to find a book for my son from when I was a kid. It was one of my favorites. I think it might have been published through the Weekly Reader Book Club but I'm not sure. All I remember is that a loch ness type friendly monster was in a small lake, and that children and maybe adults were bringing him pool floats as friends. I would like to know the name or possibly the author. Any help will be appreciated. Thank you!
