Today, I welcome author and public school teacher Matt Posner to share some of the challenges of work/writing balance in a teacher’s life. Matt is the author of the School of the Ages book series, set in America’s premier magic school, and co-author with Jess C. Scott of the Teen Guide to Sex and Relationships. Read on to hear Matt’s thoughts on “Being a Teacher Who Writes,” and learn how to find Matt online. Thanks for inviting me to appear on your blog, Summer. I write books for ages 12 and up. I don’t know who my readership is — my reviewers are mostly adults who like YA books. I hope I have reached some teens also, because I have things to say that…
