The Picnic Basket
Read books, write reviews. This is a web site you will want to bookmark as titles are offered first come first serve basis, with limited numbers of preview copies available. This site has really helped give me an edge in knowing what books to get into my classroom and keep reading engagement up high. Even if you don't get to preview the book yourself, reading the feedback from other readers is helpful in making decisions also.
Another site you might want to try is NetGalley. Discover new and pre released reading from all genres. Download to your computer or Kindle and give feedback to the publishers.
