Evolution of a series cover

In the book world, both indie and traditional, common knowledge is that one should occasionally recover and repackage a long-running novel or series. I run into this all of the time when I teach. Even though I assign the same booklist, the covers keep changing from year to year!

Recently, I attended an "author mastermind" conference that involved branding and taking one's authorship more seriously. Upping one's game. It seriously kicked my you-know-what! It also inspired me to take a hard look at my covers, my promo style and release schedule. In this post I'll focus on my Fireseed series covers.

Here is the evolution of the first two of the Fireseed novels, Fireseed One and Ruby's Fire over time.

Oldest, on bottom:
When I launched the series in 2011 I wanted to break out of the YA trope of girls in gowns, and even from the photo retouched cover. Coming from the art world, I also wanted to include my own interior illustrations. I hired digital cover artist Jay Montgomery, who taught at the Savannah College of Art and Design. I designed the roughs. These worked for a while as they attracted attention from their unique look. But I decided to scrap my interior illustrations as some thought they made the book seemed aimed for the 9-12 year-old set. They are meant for older teens and adults. And though the covers were an homage to the classic 50s sci-fi covers, they also began to seem dated.

The big portraits, next oldest:
Najla Qamber designed these next incarnations, with close-up heads and a more trendy type font. These sold quite well and I was happy with them.

The edgy setting covers, second to top:
Then, I hired publicists, who convinced me YA sci-fi covers no longer featured up-close faces, but had object covers such as the Hunger Games crests or otherworldly settings. We looked at the top 100 YA sci-fi on Amazon, and I took the bait. Again, Najla delivered spectacular covers with a futuristic title font. The look was sophisticated, gritty - everything I love. But the covers did not sell as many books. Ultimately, I realized that in YA, and even in adult fantasy, people are drawn to, well PEOPLE!

The brand new 2019 covers, on top:
In a meeting with a mentor from the author mastermind conference, we looked again at the Amazon top 100 in YA sci-fi. Yes, we still saw object covers, but we also saw a resurgence of faces and human figures, which filled me with relief. The lead characters in this newest set by Najla are in mid-picture, walking or standing in front of spooky cool settings, the hallmark of the series. It's a burning sky, it's harsh desert, it's strange jutting rock formations and thorny Fireseed blossoms literally on fire. It's topped off with a big, brash title font that reads clearly from a thumbnail.

Who knows if and when I'll design another set. There's something I love about each rendition. Which one do you like best and why? Have you recovered and repackaged your novels? If so, what prompted it?
