Reviews are incredibly helpful to me because the more reviews a book has, the more Amazon promotes your work for you--and the more promotion I get and readers I have, the more time I can devote to writing new work instead of trying to hawk my wares! They don't have to be long or fancy, I promise. Even the simplest comment like, "Great read!" or "I loved it," or '"The only thing that could've made it better was if it had unicorns" really, really, really helps.
Thanks A Lot!
