The stunning love child born of a human and an alien holds the cure to a pandemic on Earth in her genome. While the humans await a rescue ship 25 light years from home, they must also keep the xenophobic aliens from exterminating the ‘abomination’.

This is classic science fiction genre of adventures in space centered on the characters. I designed this cover entirely myself using Word, Live Photo Gallery, and Paint layering three images which I credit in the front matter. I’m not sure about the pod, lower right. It seemed boring without it. Thanks for your opinions!

Nathan says:

The problem here is that while the main image says “SF,” it doesn’t say “SF adventure.” If I were to look at the cover and guess about the story, I’d probably think that it’s a tale of exploration and isolation like The Martian.  Take a look at how classic SF adventure novels marketed themselves; there was action, usually involving characters, not just spaceships.

That’s aside from the technical problems here: The spacing on the subtitle just looks weird, the font for the byline looks like it was chosen at random, the main landscape image is artifacted, and the pod is pretty clearly added to the image.

My advice to you is a common bit of advice around here:  Pick the books that you expect your readers to compare your book to, and look at how those books are marketed.  (Also look at how they were marketed originally, if they’re classics.) Covers like that are how your target readers are used to being marketed to.

The author says:

Lilly and her friends, Hannah and Erin encounter the Spirit realm. Consequently, worlds collide. Spiritual warfare becomes a reality when an unseen enemy stalks and attacks determined to steal their destinies and ultimately destroy them. Young Adult to Adult audience. Set in in the middle of two diametrically opposed worlds, the natural world and the unseen supernatural world.

Nathan says:

I like it.  I’m not sure how well it works for this book — I’m far more attracted to the cover than to the description, which leads me to suspect that this cover may not match this book perfectly — but I like it.  I think the byline could stand to be larger, and the obvious superimposition of the chain and cross on the forearm gives the impression that the entire forearm came from another source, but other than that, I have no comments.

Anyone else?

The author says:

Set 200 years in the future on a massive spaceship named the Aldrin. Obviously it’s Sci-Fi. The target audience is sci-fi fans that enjoy Battlestar Galactica and Star Trek. Do I need a picture of the Aldrin on the cover?

Nathan says:

Short answer: Yes.

Or people inside the ship. Or outside the ship.  Does it all take place aboard the Aldrin?  Are there space battles?  (The title has at least the implication of military SF.) Do they explore alien planets? Is there something you could show that’s more than just space?

The author says:

In Bologna, Italy 1600 Katsi Cataldi is betrothed, but when a Queen is killed almost a continent away. It has far reaching consequences for her family. She will team up with a reluctant royal, Rhea Von Holt to clear her parents name. But the witch Drusilla has other plans for them.

Nathan says:

Before I read the description, before I knew anything about the book, my very first thought on glancing at the cover was, “Flame doesn’t work that way.”  Even after figuring out that they were swords of fire, my initial impression sticks.

More than that, though, I think you’ve got a cover that doesn’t advertise the book you’ve written. 17th-century Bologna is an opulent, visually enticing setting; some of that should be visible on the cover.  What you’ve written leads me to believe that romance is a big part of the book; I should be able to see people on the cover.  And not only does the font you use say “LOTR-flavored high fantasy” rather than “Italian fantasy,” the three variations you use — spaced, vertically stretched, horizontally stretched — don’t work well together.

(And this is beside the point, but I hope that the book itself is much better copy-edited than the description you gave me, which a half-dozen punctuation and grammar problems in 50 words.)
