Just to share this lovely review that I got on Amazon:
Hooray! Aaron Gray and the Dragon War is a children's book that actual ten-year-olds actually enjoy. And ten-year-old boys too, who are traditionally a tough crowd to please!
This makes me very happy!
In answer to your question, I know what's going to happen in book two and have written lots of notes about it. In May I'm going to sit down and carefully turn it into a proper story. Then I need to edit it a million times and get it ready for publishing. I think it's going to all be ready for you to read it in October 2018, which isn't that long at all when you think about it.
In the meantime, there are short stories and other things related to Breveny every Wednesday on this blog, plus other stuff every Monday and Friday. You're welcome to have a look!
