I understand the hook has to be contained within the first paragraph or two, but I have been told to explain what is going on within the hook also. I dont want to explain too much as I would like to draw the reader into the novel. How much do you "give up" in the first chapter of your novel?
I'm guilty of poor opening chapters. The rest of the book will be pretty sound, but I have a habit of trying to do too much in opening chapters, even opening paragraphs. You'll be heading down the same road if you become consumed with getting out too much info, or with explaining in advance why things happen, or giving us the MCs BG right away. Use subtlety and maybe focus on an event that will later tie into the main story; I hate giving blanket advice like that, as if every story is the same. But maybe this will help you find the right beginning for
your story.
I finally have an opening chapter that generally does hook a reader (judging from the SYW comments). The characters reveal just enough about a "situation" rising to keep reader interest, and there's just enough description to keep the reader's bearings. Their BG or backstories are only hinted at in dialogue. I try not to be coy or too enigmatic about details, that would just piss people off. But the major plot isn't even touched in the first chapter.
My chapter is far from perfect, and I'm not saying my opening is a shining example of how to do it... it just works for me, or at least, works better than what I tried before. But compared to what I had before: gimmicky opening lines, expository explanations/descriptions that were unnecessary, too much happening at once... I'm far better off.
I learned to focus and don't try to accomplish everything in the first few paragraphs anymore. I now treat my opening chapter like a short story that stands on its own with a bit of a cliffhanger at the end, regardless how much or little it bears on the main plot. Of course, the events in that opening chapter are relevant to the overall story as are the characters, just I'm more subtle and patient.
Hope this helps.
