Get published already...

So you've written the next Harry Potter... No one cares. Unless you're published. If you think that you've created some sort of masterpiece that will take you on the same path as J K Rowling to be richer than the queen some day, make sure that the people who matter, take a look at it.

First of all, you need to have your killer idea developed in to at least an outline.
If you think you can do the whole book or a few chapters, then that would also be good since that way, the publishers can make a decision based on your writing style as well as your idea and plot line.

U SPOILZ it

The next bit is the fun part. But it could be annoyingly frustrating and you may be tempted to commit murder at one point. But, this is necessary. Round out a few trusted people, these could be your friends, family or spouse and let them read your book and listen to their feedback. Your style may not be to their taste but, you'll at least be able to correct those typos and grammar mistakes and (shudder) plot holes!!

I said plot hole... plot hole

Step three, now that you know that your idea doesn't completely suck, start looking for publishers. If you're from the UK, looking for UK publishers would be a better idea. Check out their web sites before you send out your manuscript to make sure that the company accepts your genre.

CAN'T HAS FaNTASY

Next up is to actually send your manuscript out. Now, if you feel like using regular mail it's entirely up to you. But they won't be able to guarantee a safe and undamaged deliver. So, contact a courier services UK to make sure that your manuscript reaches the publisher in perfect condition and without dog ears and missing pages.

Lolcat did it!

The next step is to wait and prepare yourself for rejection. True, your idea may be the most awesome idea in the world for you and your friends, but a publisher might think otherwise. So, exercise patience and try not to send angry responses for those rejection letters and keep your head up, the right publisher for your book is out there somewhere...

...publisher!!

If all else fails, may I suggest self publishing? Not many authors have gone this way but it's definitely worth a shot.
Good Luck!
