Is there an author that is on your auto-buy list? Any time you see a new book from them you know, without a doubt, it will be great?
For me, this usually means that the author has written in multiple series or several strong stand-alones and really proven their strength. One great book won’t add them to this list.
*These ladies only have one series each but I love those so much that I know I will devour whatever comes next.
