How Much Are Indie Authors Really Earning?

What the latest data tells us and what it means for you.

Digital Book Nook recently caught up with P.E. Klein, author of “The Invisible Hand: A Pareto Sisters Mystery.” We are excited to share this insightful interview with our readers today. 

When did you first discover that you enjoy writing and wanted to become a published author?

I’ve been writing since grade school.

What is your favorite and the most challenging aspect of writing?

Working through the professional editing cycles was challenging. I enjoy getting feedback from my adult daughters about my writing. They seem to appreciate my quirky sense of humor!

Tell us about your latest release.

The Invisible Hand – A Pareto Sisters Mystery was released in June. It has won a few awards and reached #1 in its Amazon category. It’s great so many readers enjoy the book and want to see more of the Pareto sisters.

How did you come up with the title of your book?

There are many story tie-ins to the title, including the reference to Adam Smith’s “invisible hand” (of capitalism). Readers try to guess who or what wields the invisible hand of power in the story.

What do you hope readers are able to get from reading your story?

I hope readers enjoy the humor — and don’t take the book too seriously. It’s unbelievable the type of feedback I’ve gotten from some readers. A few readers actually think I’m trying to sell merchandise (the merchandising is complete fiction, like everything else in the book) and criticize the father character in the book (as if he’s an actual person). Some readers have suggested that I’m corrupting young minds. I never dreamed my book would cause such a stir. For some, the world is a very serious place.

Who are some of your favorite authors?

Impossible to pick just one, but Joseph Heller’s “Catch-22” is a masterpiece.

Do you have any advice for writers looking to get published?

Do not compromise on editorial talent. Editors are critical members of your team.
