While I'm working on book 4, I'm also looking through some detailed feedback on book 3 I got on the book before I seriously revamped it. Some of that feedback still applies, but I'm also getting feedback on the rewritten version. I want to make it as polished as possible. I'm also hoping to get another beta reader for other books in this series, and this is supposed to be a way to do it.
Meanwhile, I have also had the recommendation to see if I can join a national children's writers' group to make connections that may help either publish or spread the word on both Doomimals and Just Us Chickens. I would very much like as wide a readership as possible. I have a hybrid publisher standing by, but it would be nice to find a traditional publisher with a wider readership. I just know that chapter books and middle grade fiction often are hard to traditionally publish. I've tried some already with agents and publishers. My friend, who is actually in the publishing field, suggested that the first three books of a middle-grade fiction may be enough to get someone interested but also indicated the nature of middle grade fiction is that it is hard to get published.
One way or another, I will bring it to a publisher soon. It may be traditionally published, or it may be via my hybrid publisher I've mentioned. One way or another, I hope to make it available to you soon.
