At last, the US Kindle store has a review of Saronna's Gift. Reviewer M. Sutton gave it four stars. She wanted more sex (the reader has to wait a long time and nothing overt happens on the page) but she called it a good read and praised the lack of typos and grammatical errors, so I call that a good review.
She mentioned she borrowed the book through Kindle Unlimited. I checked and the review shows up on the paperback version, too, so they are fully linked.
