Well, it's not science fiction, and it's not fantasy.
I'd describe it as a juvenile/young adult-category fanfic based on a series of computer games I've been playing for the past few years.
It's pretty tame stuff, about a group of park rangers in a fictitious national park in the Rocky Mountains. It's supposedly set in the U.S., but I noticed the people who created it were borrowing shamelessly from some well-known scenes in Canadian national parks, so maybe I'll just hijack it across the border.
Since the last few games have actually had a basic plot, I wanted to see if I could string the rest of them into an actual story of some kind.
It's a different kind of challenge than turning a solo 2nd-person pov D&D-type gamebook into prose. Vacation Adventures: Park Ranger is what's known as a Hidden Object Game, and the 7th installment came out a couple of months ago. That one had a plotline of trying to catch a poacher, so I figured, why not flange up a plot for the whole series?
Inventing new characters and fleshing out the established game characters has been a challenge, and I've been winging it a lot of the time. This project is going to take research, but I'll admit that I'm drawing on my own experiences traveling in the Rockies and the Alberta/British Columbian national parks to describe the setting.
So... as I said, it's really tame, compared to other projects. No humans are going to get killed, nobody's a mage, it's not dystopian space opera, and it's an attempt at a real-world vacation adventure. The biggest challenge is trying to figure out how and why all the hidden objects got scattered around where they are. Why is there a pizza on the roof of the entry to an abandoned mine shaft? Who brings a fancy violin along on a camping trip, and why? What's the reason for part of the park entrance sign being found in a nearby bush? How do the Rangers get around that huge place, to all the different locations, since logistically speaking it's too far to walk the whole way?
In essence, it's a fanfic based on a series of games. But I've played and replayed this series more than once, and felt like trying something different that doesn't require so much prep. Of course I'll be using the time between now and the summer NaNoWriMo to do some more research, and jot down some ideas for characters' personalities and backstories. Haven't decided on whether to include any sort of romantic subplot. I gave the Chief Ranger a wife, but she's never a character in the game, so maybe that will have to do.
