Some writers have day jobs; some teachers write “on the side.” Gordon Jack does both — and neither. On the one hand, he spent more than a decade as a classroom teacher, has taught teachers and is now a high school librarian. On the other, his upcoming second YA novel, Your Own Worst Enemy, is garnering the same kind of rave reviews as his first, 2016’s The Boomerang Effect. This week, Jack joins the GrottoPod to talk about juggling two careers and explores high school, teenagers, controversial subject matter, his writing process (hint: it includes trains) and his home’s proximity to that of a certain GrottoPod host.
