I've been meaning to tell you about this. I recently discovered the blog of author Sarah Duncan and had to bring it to your attention. It's an absolute treasure trove of excellent writing advice for those aspiring authors among us.
Not only does Sarah write marvellous Rom Com books, she also teaches creative writing at the Universities of Oxford and Bristol. She knows her stuff!
So take a peek, but be careful not to get locked on (like I did), else you'll be so caught up in reading about writing that you won't actually, you know, do any writing.
