I'm 18 chapters into it, planning to finish by the end of this year and then be brave and try to attract agent interest.
It's going reasonably well at the moment, so fingers crossed I can keep up the momentum.

Just had a look at your blog, well done for getting your 'platform' together in advance of publication!
I think I'd be careful about posting too much of your novel online, though - published authors will be able to advise better than me, but I'm sure I've read that anything more than snippets could end up causing difficulties further down the line.
Best of luck with this, though
