Dear O'Abby: What's a hook and do I need them?

 Dear O'Abby,

My crit group keeps saying the same thing about my chapters: there's no hook.  

I'm not sure what they mean by this or why they seem to think I need one in every single chapter.

Is this something you know anything about?  I'd be grateful for any clarification.

Kind regards,

Hookless

Dear Hookless,

A hook is a device in a book that makes the reader want to keep reading.  The first line should act as a hook, drawing the reader in and making them want to read more.

But in the context you've given, around each chapter needing a hook, I'm thinking your crit group is talking about having a good hook at the end of each chapter to make the reader want to keep going.  Think about it like a cliff hanger.  You want to end each chapter with a tantalising reveal about something, a piece of action that leaves your character(s) in peril or a piece of information that changes things for the characters.

Obviously your book isn't going to be pitched at a consistent level of tension throughout, so the hooks at the end of each chapter don't need to be huge every time. It would be too exhausting if every chapter ended on the same kind of note!  There just needs to be a reason for the reader to want to turn the page and keep reading rather than putting the book down.

Hopefully that helps?
