I wrote a little book, Welcome to Tragedy: A Beginner's Guide to Greek Drama, with brief introductions to all of the surviving scripts by Aeschylus, Sophocles and Euripides (plus three comedies by Aristophanes). I was fascinated by the variety of Greek drama, ranging beyond familiar definitions of "Tragedy." One script that really sticks out is Euripides' Helen, a wacky swashbuckling adventure story. So that chapter is here (starting at about the 8 minute mark), after a basic introduction to the Trojan War.
