I subscribe to Bookbub a free service that sends me a daily email with bargains on ebooks based on broad categories I picked. Most of the time there are a couple of free books on a subject I like.
Today, one of the free books is geared to help authors in writing and avoiding some common pitfalls. The book’s title is “Dear Writer, You’re Doing It Wrong” it is by Becca Syme and I thought it might be something that might prove useful. The book is currently offered for free by Amazon, Barnes and Noble, Apple Books and Kobo for a limited time.
Anyway, I hope this helps you!
