FWIW I found that by looking at the Samus Is a Girl Literature section, and one of the first items listed has got Jack as a spoiler.

There was a book I read between 2002 and 2008 that I picked up at a library. It was in the Young Adults section. The book was about a group of kids/teens being sent to to an alien planet to survive. On of the kids got torn to shreds by a dog or dog-like creature. And one of the characters, Jack, everyone thought was a guy, turns out is a girl. That is what I can currently remember of the book. I'm not sure if it was a stand alone title, or the start of a series, but either way, I'd love to re-read it.
