Fair enough. I guess we just do have differing viewpoints, and the fact that this is the first book of a five-book series tells me that many of these moments will pay off in the future. But I can understand the desire to see the pay-off right away.
It's not just about immediate gratification. It's about any
gratification. The first chapter hints at the disastrous event. That's the hook. The rest of the novel has almost no bearing upon it. When the novel finally does turn to satisfying the hook, it's too late, and the novel is over. You've just read all those pages without the hook ever being resolved.
