There aren't that many competitions for writing for children and here's one from writing.ie
The A. M. Heath literary agency have announced a Irish Children’s Prize, looking for a new standout Irish voice in children’s fiction.
The Irish Children’s Prize will be judged by Julia Churchill, children’s book agent at A. M. Heath, and David Maybury of Brown Bag Films, Penguin Children’s Books and Inis Magazine editor.
Literary agent Julia Churchill (pictured) said “David and I love all sorts of writing for children. The winner could be a 200 word picture book, a sophisticated YA novel, a 9-12 stand-alone, or a young chapter series. I’m looking for a strong voice, a character to love, and a concept that feels fresh. If you’re writing for children, we’d love to see your work."
It is open to un-agented writers living in the Republic of Ireland and writing children’s or young adult fiction in English. To get a good sense of the voice, concept and where the character is headed, we’d like to see the first 5,000 words PLUS a short description of the book (a few lines) AND a one page outline that shows the spine of the story.
Deadline: October 17th.
