I believe that many cultures have stories in which young people triumph over forces because versus adults kids think more outside of the box, just because they're not old enough to "make their own decisions" (as some adults say) doesn't mean that they're not smart enough to handle themselves. Kids also don't let weakness get to them they will keep going without giving up. Some kids books that are "Kids Vs Evil" are.. Doctor Sleep, The Death Path, Wonderland, etc.
