BookSirens was founded in 2018 — initially as a directory to help authors quickly find potential book reviewers in their genre and to help readers get complementary books in exchange for their review.
Since then, it has evolved into a vital tool for any author or publisher looking to launch their books with more social proof via honest book reviews on sites like Amazon, Goodreads, and others. As of May 2025, ~11,966 authors and publishers have promoted their books on BookSirens. They include Amazon Top #100 authors, NYT and USA Today Bestselling authors, and promising debut authors across almost every genre.
The availability of advance review copies (ARCs) in a variety of genres has also made BookSirens a household name among the book reviewer / ARC reader community. Our audience of ~51,607 readers has written over ~619,372 voluntary reviews on sites like Amazon, Goodreads, BookBub, Barnes & Noble, Kobo, Google Play, and Apple Books, with more reviews being written daily.
