Interview with Costi Gurgu, Author of Black Corrosion

06 Aug 2025

What’s the story behind the story? What inspired you to write Black Corrosion?

I wrote the short story “Corrosion” for National Geographic Magazine. It won three awards and was resold five times. Then, an editor asked me to write the novel. Black Corrosion is Book 3 of the Corrosion series. We, as a species, are reaching a breaking point in our relationship with Nature. Earth will survive whatever may come, but will humanity? Take water, for instance. Indispensable for life and still abundant on Earth, it does its job to keep us alive and well. What if water changes its properties as a result of pollution? It could kill us—or transform us. Read the Corrosion series to find out how.

If you had to pick theme songs for the main characters of Black Corrosion, what would they be?

“Wild Boys” by Duran Duran.

What’s your favorite genre to read? Is it the same as your favorite genre to write?

Yes, I love speculative fiction. Be it science fiction, fantasy, horror, or any sub-genre.

What books are on your TBR pile right now?

“A Shift of Time” by Julie E. Czerneda and “The Paris Wife” by Paula McLain.

What scene in your book was your favorite to write?

There is a scene where one of my main characters, a scientist, is called to observe and find a solution to combat a plague that has hit the community. She’s used to the modern technologies from back home, but right there in the heart of the new world, there’s no modern technology, and she has to adapt to the primitive reality of her surroundings.

Do you have any quirky writing habits? (lucky mugs, cats on laps, etc.)

I need my Star Wars mug filled with iced coffee and appropriate instrumental music to put me in the mood for writing. The music depends on what I’m writing at that time.

Do you have a motto, quote, or philosophy you live by?

If it’s weird, write it down.

If you could choose one thing for readers to remember after reading your book, what would it be?

That no matter how different we are, our humanity is the common element.
