If I review a book, I give an honest review of my thoughts. If it's an advance reader copy (ARC ) the actual review page will have further details in the FTC section and try to connect my readers to a description/ synopsis of what the book is about, my thoughts, and links to the author or a photo from the galley packet.
My stock pile is set up, so reviews appear even when I am not actively reading. You can find my reviews with Net Galley, Goodreads, LibraryThing, Amazon, The Crown Publishing Group, Pleasant2View and also with libraries who use reviews to expand their collections.
My star system, below, is available to publishers when I have read and reviewed their galley. And, sometimes their departments write and ask for further details or tell me when and where they will be posting another galley for review.
1 star: strongly disliked it
2 stars: did not enjoy reading
3 stars: occasionally enjoyed it
4 stars: really enjoyed it
5 stars: adored the writing, plot, message, or perhaps I loved all of it.
