Go to any small, independent bookstore and you are likely to find the most current issue of the Booksense newsletter. Each month, a list of book recommendations is compiled, based on recommendations from independent bookstore employees. There are also specialty pick editions that focus on a specific theme or genre. These books might not all be on the best seller lists, but they are wonderful books nontheless.
The Bookshelf at Mommy Track'd has book reviews as well as a comprehensive list of reading recommendations all of particular interest to working moms. You will find Books About Balance, See Mom Work Books (featuring kids books where the mom character works), Working Mom Fiction for your Non-Existent Free Time, The Anti-Princess Reading List for kids and more.
