Ten Arrows of Iron follows Seven Blades in Black in the series The Grave of Empires by Sam Sykes and continues the story of Sal the Cacophony. Being a fan of the first one I had to check out the second. Here's the Goodreads blurb:
The second novel in an epic fantasy trilogy that follows an unforgettable outcast mage caught between two warring empires.
Sal the Cacophony-outlaw, outcast, outnumbered-destroys all that she loves. Her lover lost and cities burned in her wake, all she has left is her magical gun and her all-consuming quest for revenge against those who stole her power and took the sky from her.
When the roguish agent of a mysterious patron offers her the chance to participate in a heist to steal an incredible power from the famed airship fleet, the Ten Arrows, she finds a new purpose. But a plot to save the world by bringing down empires swiftly escalates into a conspiracy of magic and vengeance that threatens to burn everything to ash, including herself.
