I’ve been an author since 2013. These are a few of the products and services I use every day and the groups I have found informative and supportive. I don’t list anything I haven’t tried and found useful.
I highly recommend Inkers Con and Author Alessandra Torre’s courses. They've been a tremendous help to my writing career. Another thumbs-up from me is Gwen Hayes's Romancing the Beast course (Romance Writers of America). What I learned from that course helped me structure my writing and refine my voice. If you're unable to take the course, the book is fantastic (see below).
