Just as a status update: my current best guess is that the final book in the They Who Fell series will be out roughly this June. That could get delayed some with editing, formatting, deciding I want to polish it, etc., but that's what it looks like right now.
I'm also expecting to publish a completely different book soon (next week I think) based on the Greek myth of Jason and Medea. It's a science fiction retelling of the story of a group of Greek warriors who go on a quest to a foreign city searching for a treasure called the Golden Fleece. They're led by Jason, a warrior who falls in love with a barbarian sorceress named Medea, and they fight a bunch of strange monsters along the way.
It's something I've been working on part time for a while, it's been a lot of fun writing it, and I hope you'll enjoy it.
