Thoughts on The Eye of Minds

What I think about the Eye of Minds is. It's really good but Kaine the hacker is really that good at hacking? The VirtNet should be able to stop him or use their millions of dollars to find him. Unless he is one the richness kids in the world and no on can find him. My second thought is when they go to Devils of Destruction and their guns don't work. Why would they get guns, grenades and they won't work? Do they have to make their weapons? There surrounded by snow, caves, blood and people. They should be able to get different kinds of weapons once they kill more people. Last thought, if Kaine  realizes that he will get found soon by those three kids, then he should send bodyguards when they get close to find him.
