I love kid's books - mostly because they're not just for kids (and I speak as both a reader and a writer).
I was going through some old posts and found one from Oct 06, in which I declared Subversive Children's Literature Week and offered some suggested reading. If I had to pick one from that list, I'd go with The War Between The Pitiful Teachers and Splendid Kids, by Stanley Kiesel. Holy cow it's a great book, and more than any other it is responsible for inspiring my own Boomer Sisters series.
What's so subversive about these books? And what's so great about subversive literature? I'm glad you asked. These books are all designed to make people think. They encourage questioning of the status quo. They are great stories, well told, of people who dare to be themselves and who help other people on the journey. They are full of love, self-sacrifice, creativity and imagination. They do wonderful things to people who read them.
