Devil's Gun (Disco Space Opera, Book 2)

When Niko and her crew find that the intergalactic Gate they're planning on escaping through is out of commission, they make the most of things, creating a pop-up restaurant to serve the dozens of other stranded ships.
But when an archaeologist shows up claiming to be able to fix the problem, Niko smells something suspicious cooking. Nonetheless, they allow Farren to take them to an ancient site where they may be able to find the weapon that could stop Tubal Last before he can take his revenge.
There, in one of the most dangerous places in the Known Universe, each of them will face ghosts from their past: Thorn attempts something desperate and highly illegal to regain his lost twin, Atlanta will have to cast aside her old role and find her new one, Dabry must confront memories of his lost daughter, and Niko is forced to find Petalia again, despite a promise not to seek them out.
Meanwhile, You Sexy Thing continues to figure out what it wants from life―which may not be the same desire as Niko and the rest of the crew.
