If you found anything to interest you in my thoughts below about getting into Angron’s head and portraying him as a compelling character, then also pop over to this post on Gillian Polack’s blog which has some really good insights on how characters’ thoughts, actions and behaviour interact with reader expectations.  Gillian has a great way of drawing on personal experience to underpin points about fiction and storytelling, and she does it with a warmth that serves the point much better than my own writer’s eye, which tends to be rather too detached and chilly.
