Blacksun Book Reviews is an independent book-discovery and author-promotion service for indie and self-published authors. We research how books are represented and discovered across Goodreads, Amazon, BookBub, StoryGraph, LibraryThing, Hardcover, and search.
Our work includes book-specific discovery strategy, author-profile and listing guidance, platform positioning, and clearly defined promotional support.

Book discovery is shaped by accurate metadata, complete author profiles, clear book listings, platform rules, and genuine reader interest. Blacksun helps authors understand and strengthen those foundations through practical guidance and clearly defined promotional work.
Strong books are often overlooked when author profiles, book records, editions, series information, or metadata are incomplete or inconsistent across the places readers search.
—About Blacksun
Discoverability depends on whether a book and its author are accurately represented across the places readers search, browse, save, compare, and discuss books. Blacksun reviews those public discovery pathways and helps authors improve the areas most relevant to the book. The discoverability footprint guide
