I've been on both sides of the beta reading spectrum in my journey to write my first novel, The Harvester. Rewarding is the best word I can think of right now when I think of both the experience in beta reading for others as well as the experience in working with people who've read my manuscript. My friends have been wonderful and this past January I joined a writing group and the past six months has been a whirlwind of discovery.
That said, know that whatever I say here are the words of a beginner. I know nothing. I am learning as I go.
