Trag, our characters won't actually like each other much. Mine will see your's as slightly arrogant and too much of a risk taker with adults, they will think she has no sense of self-preservation and seek to avoid her to keep themselves safe. Plus, she seems like an adult to them, a figure of authority that would bring the hammer down and destroy what is left of them.
Hey Sam, may I suggest a trail for the children to overcome?
Quin, read the Darren Shan Saga, it's amazing. Almost anything by Stephen King is decent and if you're into manga read Saiyuki and Saiyuki Reload if you like gore, violence and cursing. As well as some mild suggestive themes. It's rated 16+.
