I'm not getting why this matters at all. Maybe you'll find out a cute author's work isn't your style and don't read more. Maybe you'll find out the work is exactly your style and read everything. Maybe you'll see more pictures and find out it was just one really good head shot you saw at a stop light one time and the crush has passed.

In any event, remember it's an author, you don't know them, and keep an appropriate distance and perspective.
