It's the reviews that we get from friends that always make us smile, but the one's we get from complete strangers are the one's that make us sit back and evaluate how we actually "perform" as writers. Each time I get a request to post a review or interview, I shudder just a little bit. What if they don't like it? That thought gnaws at each of us no matter how successful we are. I am only an aspiring write with my one book in publication. Luckily I have 11 reviews from various people that actually like it! (At least I know that 11 people have actually read it! The most recent is from Katy Walters of Southern England. She is the author of Phobic Dawn (I highly recommend it) and a sci-fi book reviewer. Here is the link: http://katysreviewsandnews.blogspot.com/
I highly recommend that you check out her blog as well as her book.
Also, if you get a chance, every time you read a book, please reach out to the author through email, Amazon review, or Goodreads and let them know that you appreciate their work.
Kind words go a long way!
