If you write kidlit (YA, MG, Picture books, Chapter books) you HAVE to be online August 16-18 for the WriteOnCon. It's a totally free, completely online conference. I'm talking blog posts, vlog posts, Live Chats, and Query Critiques. Feedback on your first few pages, your synopsis, and the watchful eyes of agents and editors in the forums.
Seriously. Published authors, agents, editors, and a ton of writers. Why on earth would you miss it?
