Jack has a dead end job and no life, when he's suddenly offered a job with a great salary - he doesn't know anything about it, but he takes it, as it has to be better than what he's doing now. At a top secret facility, he's asked to look at some strange objects, photograph them, and describe them. When he finds he can interact with the, sometimes deadly, objects without coming to any harm, suddenly he's hot property.
Sounds like an interesting plot. It's actually written more like a 15 year old boy's adventure story: there's no real plot or development, and he's one of the most juvenile, selfish, self-pitying, nasty bullies I've read about. And he's supposed to be the 'hero' (or anti-hero). He truly believes all his problems are caused by other people, they're never, ever, his fault, and he even hates, really hates, God for not taking a personal interest in his life, solving his problems, and making it as great as he deserves. His boss gives him a hard time because he's a petty little man worried about his job (not because Jack is actually being an arrogant idiot). His previous girlfriend ditched him because she was a horrible person who didn't give him the respect he deserved (his attitude to women made me want to punch him). There are other words I could use to describe his attitude to people, but I'm trying to keep this child-friendly. And it goes on.
I kept hoping this was part of the plot, and something would happen to show there was a real person in there, but no. The ending wasn't really a surprise, and if, as the story suggests, his father is who he is, he wouldn't be proud of Jack, he'd be ashamed to be related to him.
