Definitely. I have received a lot of very valuable feedback from readers of Spring House that has given me great information to use in future books in The Westward Sagas.
In fact, readers of my blog at http://westwardsagas.com/blog have given me great help in learning about specific historical characters.
I have a group of beta readers who check facts for me as well as point out anything that needs to be clarified or changed.
My readers are a great source of help and information for me.
