Local TV news reporter deals with a worldwide plague of antibiotic resistant bacteria, a conspiracy to cover up a new skin disorder in children, and his old high school nemesis forcing himself back into his life.

Although Brutal Adaptation could be considered a modern medical mystery, the science fiction elements of the story are too strong not to consider it sci-fi. It utilizes an around the corner type of science that was used often by Michael Crichton, without the embedded action sequences.

This is a test of concept for a replacement cover for my existing novel. One thing I am concerned about is that the font on this image may make it appear to be a horror story, which it is not.

Nathan says:

Whenever anyone introduces a cover as a replacement for their current cover, I like to seek out the current cover for comparison:

So yes, the new cover concept is an improvement.

I think the new font has other demerits before you get to the question of it looking too much like a horror novel; it’s also nigh unreadable, and even worse at thumbnail size.

And if looking too much like a horror novel is your concern, then definitely DON’T include a little girl and her teddy bear — anywhere other than a children’s picture book, that just screams “horror novel” to me.

I’m also not a fan of the biohazard symbol, if only because it’s so overused these days (and half the time, you see it on the cover of a zombie apocalypse novel — yet another false flag for horror novels).

You mentioned Michael Crichton as an author with comparable appeal. Obviously, it’s a problem taking cues from the covers of Michael Crichton novels, because the most important element on those covers is the big name “MICHAEL CRICHTON,” but let’s take a look at the “medical thriller” category, where you’d find such novels as The Andromeda Strain:

Here’s what I’m seeing: strong and clear type that dominate the “real estate” of the cover, and a single central image.  A lot of reds, which seems to correlate with how “medical” the book is.

So: Find a simple image that says “contagion” or “infection” — a broken test tube seems to fit the bill.  Either a dark red background if it’s a very “medical” story or, if your story concentrates more on the conspiracy as it sound like it might from the description, some other dark color. Clear, untextured type above and below the test tube, and Bob’s yer uncle.

Genre: YA Sci-Fi

Nathan says:

Well, you’ve definitely hit the bull’s eye on genre identification.  This has “teen spec fic” written all over it. I’ve only got two design notes:

1. Apparently this bugs me a lot more than most people (because if it bugged other people, it would be nearly so common): I hate italics which, because of the angle of the baseline, still tilt left.  If your goal were to make ME happy specifically, the title type would align either with the horizontal building fronts or with the vertical edge of the cover itself, and the latter’s probably a better choice. (The fact that the tagline is also at a different angle just exacerbates the problem.)
   
2. The series title could stand to be lighter and more readable — at the very least, I’d make it the same color as the title interior, rather than the title outline.

Book about how to remove cellulite

Nathan says:

I’m always hesitant about giving advice across cultural lines. (I’m especially hesitant when it’s Polish culture — if you’ve seen how odd their posters for American movies seem to American eyes, you know that there are some very different standards at work.)

However, judging by the American standards which I know best:

• Google Translate tells me that the title is “Effective Methods of Getting Rid of Cellulite” in English.  Given the photograph being used, I would think that someone along the lines of “Secrets of Getting Rid…” would work better.
• This subgenre of self-help books relies heavily on specific promises — a subtitle that says “21 Days to Firmer Flesh and Younger Skin” or somesuch would be appropriate.
• Why is there no byline?

Explains what cryptocurrencies are, how they fit in our economic system, how to trade them and the risks/rewards involved. This book serves as a introduction to the world of cryptocurrencies and technical trading. Potential readers should get the idea that they could become make money with cryptocurrencies, although there are risks involved.

Nathan says:

A step forward and a step back here.  The good:

• Removing the extraneous “pirate” imagery helps to focus the cover.

The bad:

• The title typeface is, if anything, harder to read than originally.  The font also has kerning issues, especially seen around “y” and “v”.
• The subtitle font still clashes horribly.
• By reducing the size of the main “bitcoin in a chest” image, you’ve lost the added clarity you have it by removing the skull and diamonds and made it harder to “read” visually in thumbnail. Giving the Henry Ford quote more space is a mistake, as it’s not something that be read at anything less than full size anyway.

Recommendations:

• Enlarge the chest like it was on the first cover.
• Change out the fonts entirely, both title/byline and subtitle.  Remember with the subtitle that the smaller text is, the more readable the font has to be.
