The Ace of Skulls: A Tale of the Ketty JayPaperback, 25 August 2015

They've been shot down, set up, double-crossed and ripped off. They've stolen priceless treasures, destroyed a ten-thousand-year-old Azryx city and sort-of-accidentally blew up the son of the Archduke. Now they've gone and started a civil war. This time, they're really in trouble.
As Vardia descends into chaos, Captain Frey is doing his best to keep his crew out of it. He's got his mind on other things, not least the fate of Trinica Dracken. But wars have a way of dragging people in, and sooner or later they're going to have to pick a side. It's a choice they'll be staking their lives on.
Cities fall and daemons rise. Old secrets are uncovered and new threats revealed.
When the smoke clears, who will be left standing?"
