It used to be that most writers didn't have a literary agent. Now, it seems like everyone either has one, or is looking for one, or is thinking about looking for one. There's an interesting feature on the blog of Julie Hedlund called "How I Got My Agent" in which several writers tell their tale on the topic. Check it out here.
And for fun, here's a trailer for the recently published book, I See Kitty by Yasmine Surovec. If you don't see it below, click on the book above or check it out on the Macmillan site here.
