Bargain Book Reviews
Bargain Book Reviews read and review books (fiction) priced below $5 but prefer books in the 99c-$2.99 price range. They accept a multitude of genres, including science fiction and fantasy.
Where books are accepted for review, honest reviews are provided in exchange for a free copy. Bargain Book Reviews also hosts Giveaways and author spotlights.
