How important are titles, anyway?

The novel I have been working of for some time now is currently titled 'Emma and the Madhouse Kids' and sure, it sounds good.

It means there's going to be:
*an Emma.
*Kids, possibly from some "madhouse" -  whatever that means.

And those things are true.  But, believe it or not, there's actually a lot more to it than that.  Firstly, while there is an Emma, she actually isn't the main character.  She thinks she is, and in a way it is all about her, but the main character is actually Alex.  So should I call it 'Alex and the Madhouse Kids' instead?

What about those Madhouse Kids?  Well yes.  I mean, no.  There is a bunch of kids at a medical facility where experiments are done on their brain, but never once is it referred to as a 'Madhouse'.  Maybe I need to work on that.  Maybe I should just call it 'Emma'.

But maybe I can keep it as is.  I mean, think of all the books with misleading titles.  Wait.  Don't even think.  Here is a list.

The Six Most Misleading Book Titles.

1. 'To Kill A Mockingbird' -  Not a story about killing birds.
2. 'The Neverending Story' - Well the main gripe I have with this title is that it ended.
3. 'Trainspotting' - Unless that actually is a term for Heroin that I've never heard of.
4. 'Men are from Mars, Women are from Venus' - Just nope.
5. 'The Man in the High Castle' - Amazing book, but no.  The title is all wrong.
6.  'Breakfast at Tiffany's' - No.  No-one had breakfast there in the entire book.  I don't even know if you can have breakfast there. I thought it was a Jewellery store.

But you know what?  Despite having titles that just make no sense, most books on that list are amazing.  So I will stick with that title for now.  And you know what?  When I write the sequels, their titles won't make sense either.  'Kiara under the Reichstag' and 'Devendra versus the Tokyo Traitor' - well until I think of something better anyway.

Which I am certainly going to do at some point after they've been published.
