Do you need a Beta Reader? I think every writer should have at least one. Unlike your friends, they won't sugarcoat everything. They will see the flaws in your book and tell you about them. Some readers will edit line by line while others read for the story, characters, etc. Both can be helpful.
Where do you find a Beta Reader? I have heard a variety of answers on this one. I think the best place to find one is at a writer's hangout like Absolute Write Water Cooler. Although, I found my reader on Yahoo Answers.
*Blog Tour Update*
I still need a few bloggers for the Witch Hunt Blog Tour coming up in April. Most of my dates have been filled, but there are still some that I desperately need to fill. I don't want any gaps in the month of April. The tour will work better if I have an interview or guest post on a blog each day. If you are interested in hosting the tour for a day on your blog, leave your email address below or send me an email at email@example.com
