I just queried a literary agent. This is the first time I feel like I really need to find an agent. For one I've sent out 7 children's pb manuscripts for 4 years...the rejections are getting old. And now I've written an "begin to read" chapter book (3 little stories in 3 little chapters). The publishers publishing these types of books will not accept unsolicited manuscripts. I guess it's time to get some help.
