Prior to a book being published it is offered out as an ebook digital known as an 'arc' to respected bloggers and professional reviewers. The publishers organise this task through a trusted company called NetGalley, who vet their blogger/reviewers based on reliability and completing their given task - it isn't based on the star ratings they award previous books. The author and publishers want a true picture in response to potential readers, so it is essential that bloggers read and return true reports.
Here are my reviews coming in from NetGalley.
