I'm not trendy. For starters, I just this week learned about steampunk which appears to have been trendy since at least 2007. But for all of you who like me and are not yet aboard the steam train, I introduce you to my first installment of "trends for the untrendy."
My oversimplified definition for non-trendy people:
Steampunk - science fiction set in the past
The most traditional steampunk is set in the Victorian era and highlights futuristic technology as it would be imagined by people from the era, reminiscent of H.G. Wells and Jules Verne. However, steampunk can still be steampunk if it is set in different time periods and/or highlights paranormal elements instead of futuristic technology. For great examples of steampunk, check out Soulless by Gail Carriger and The Girl in the Steel Corset (Steampunk Chronicles) by Kady Cross.
More eloquent and accurate definitions from real steampunks (linked to source):
"Steampunk could be considered a retro-futuristic neo-Victorian sensibility that is being embraced by fiction, music, games, and fashion. It is ornate and vibrant, and intricate. It believes that functional items can and should be beautiful." - Cherie Priest
"Steampunk fiction is fiction that’s in love with old-fashioned gadgets and machinery." - Richard Harland
"Steampunk is an aesthetic that mixes elements of technofantasy, and neo-Victorian retrofuturism." - Mike Perschon
Although I am way late catching on to steampunk, it seems that the trend is far from over. I researched it in the first place because agents are looking for it!
Here are some agents who are looking for steampunk:
The McVeigh Agency (steampunk for young readers)
Steampunk is still steaming. Will is still be hot by time I'd be able to write and edit a steampunk novel? That's not as clear. But if you love steampunk, don't worry about the trend, just write it, read it, and love it.
