Welcome to MobileRead! Even though I'm a publisher, I will suggest that if you want to support authors, check out the many authors who post regularly or irregularly here. Read their free offerings, try their paid offerings if you can/want to, and recommend the ones you like to others. Independent and small-press authors have a tough (but possibly quite satisfying) road and ebooks really help to make it feasible to go that route in the first place!
