There are many places to find reader reviews on the web, but it can be a challenge to know which are truly independent.
The reader reviews offered through BookBrowse's First Impressions program are trustworthy because only our members can post them. Members have the opportunity to request books to read months ahead of their publication dates in exchange for their honest opinion. They can request specific titles but the books are assigned by an algorithm. So, while it's conceivable that someone with a personal connection to the book might receive a copy to review, the chances of there being enough people to influence the overall consensus is effectively zero.
Below are this year's First Impressions titles, 37 in total. You can also browse over 600 books from previous years.
