I actually had another thought about this the other day: I think oftentimes, the 'hook' can (and sometimes should) be the title itself.
Because the title can grab someone's attention and interest (enough for them to want to buy it and read it) but it also leaves some good mystery as to what the book is about. Which can make someone want to read it even more.
That's very good point. It reminds me of a blog post Grace wrote a short while ago.
I would say that there is a material difference between Hooks and Titles, and Hooks are not necessarily unnecessary (ok, that word choice was awkward...

). Titles have more requirements to be good than a Hook does. A title needs to be short, and it needs to be memorable; and generally it also has a conventional title structure (statements and imperatives aren't common). A Hook, on the other hand, need only be reasonably short, hooking, and accurate.

Some of you may recall that I sometimes have (metaphorically) violent reactions to blatantly manipulative advertising ... of the sort that screams "Read this book so you'll want to read these ten other volumes that are package exactly the same!" instead of "Read this book because it's a good book!" And I have to say that every book I can ever remember coming across (that I read any of) that had a "hook" like this prominently displayed on its cover gave every indication of being a clear case of manipulative marketing. (Some were good books regardless, mostly those dating from the "bad old days" when publishers would insist on covers, blurbs, and taglines that were only tangentially related to the book. When Ace published H. Beam Piper's Junkyard Planet, for example, they renamed it The Cosmic Computer and put on a cover, tagline, and blurb describing it as a computer-takes-over-the-world story, which could hardly be more wrong while still getting the names of characters, the planet, and the computer in question right.) So if you want me, and those like me, to buy your book ... think long and hard before you decide to put a "hook" on the cover.
* thoughtful * I know precisely what you mean, actually. I am more sensitive than most people to manipulative advertising. But I've developed a philosophy of 'keep the good ones and let the bad ones go', so it doesn't affect me as much anymore. I generally just laugh inwardly at it.

I realize that this would be a problem for some, though.
I think that generally speaking, however, people like Hooks. They're appealing to most people. At least in a lot of target areas.
In some genres particularly, though, I think it would be good to skip the hooks. I know what genres in my head but I'm not recalling any names at the moment...

Anyway, that's my take on it.
You brought up another good point, though. About accuracy. There are few things that irritate me more about a book than a hook (or any kind of description, for that matter) that misleads me about the book. I hate it. I know how hard it is to write a blurb or hook that is appealing and draws the reader, but – * tight grimace * It frustrates me to no end when they are inaccurate.
