I'm still a baby in Greek, but I've been studying it as intensely as I
can for about two months now. I've covered all the grammar in
Mastronarde, and I've been spending a long time on some readings
courses. Needless to say, I'll be very slow and bad, but I think I'll
be able to keep up with some basic stuff.
I don't know anything about it, but this has looked very promising and
hopefully entertaining for people at a lower level of Greek--plus, it
includes a full and side-by-side vocabulary:
Xenophon of Ephesos
Ephesiaca, or, Anthia and Habrocomes Book 1

Here is part of the description from the webpage: "Finished the first
year of Greek and hoping not to forget everything? Or trying to brush
up on things after some time away from Greek? Depressed trying to slog
through Pindar and looking for an ego boost? Read easy Greek with
vocabulary and some basic notes! Xenophon of Ephesos' Ephesiaka, one
of the five surviving Greek novels, is usually read in the original
Greek only by scholarly specialists. That's a real shame. Sure, it's
not the greatest literary achievement of the ancients, and the Greek
is pretty uninspired and repetitive, but that's what makes it perfect
for beginners! The language is a basic "literary Koine," so it's easy
to understand if you've studied Classical Greek, but close enough to
the simpler grammar of the New Testament that it makes a good
transitional text for people who started with the NT."
