Everything you need to know about writing a query letter, synopsis, approaching agents, conference etiquette - in fact, pretty much EVERYTHING about writing and the publishing industry. This blog is INVALUABLE!
The extremely generous Janet Reid also does The Query Shark blog in which she CONSTRUCTIVELY critiques query letters. She insists you read the entire archive before submitting a query or a question for the blog. I thought that was ludicrous until I actually did it and found I learned a huge amount about writing queries.
Another very generous blogger, Janice Hardy, has a huge archive of blog posts on planning, writing, editing, and selling your novel.
This blog has contributions from editors, agents, and authors. It's an extremely welcoming, supportive, and generous, community of writers and publishing industry leaders. I read this blog every day.
