You will be reading one of the following books this school year.  All three of these books have been quite popular, and science and non-science folks alike have sung their praises.  Read the summaries, listen to interviews with the authors, and do your own research to decide which book is your top choice.  Amazon.com, barnesandnoble.com, and newspaper sites like nytimes.com have wonderful reviews that you can peruse.  I have provided the book lengths, but do not solely use this information to make your choice, as you might be missing out on a wonderful book!
