Demon Engine by Marten Norr

Sally Delavega, the best demon-binder the world has ever seen, would do anything to banish the two hundred ghosts trapped in his head—even if it means swimming up from the bottom of his tankard. When the Navy that destroyed his life comes sailing back to offer enough coin to get the job done, Sally agrees. All he has to do is help the crew of the Steadfast track down the ancient abyssal that lies sleeping at the heart of their drowned world. Why the Navy wants the demon isn’t Sally’s problem. But as they sail on, Sally begins to dredge up disturbing truths about how the world flooded and their ancient eldritch quarry that might just want to be found… Imaginative and poignant, funny and bizarre, Demon Engine brings us a bold, queer high-seas adventure that asks how deep we might venture for what we aren’t willing to lose.

Unbound (Songs of Chaos, #2) by Michael R. Miller

Sometimes the world needs a little chaos. Holt and Ash saved the kingdom of Feorlen against all odds. Now they are outcasts, alone on an impossible quest to unite the Elder Dragons. But they are children playing in a game of Dragon Lords. Trapped between the riders, servants of Sovereign, and the scourge, even their luck cannot last forever. Their only hope is to advance their bond by any means necessary. In Feorlen, Talia faces a world unaccepting of a rider queen. Her councilors will not heed her warnings of Sovereign. Foreign powers threaten war and bloodshed. Pleas sent to rider headquarters fall on deaf ears. All the while, Sovereign regathers his strength in an ancient fortress. Enthralled cultists swell his ranks. Disillusioned riders flock to his cause. And his unwilling servant Osric Agravain scours the land for dragon eggs. There are new types of magic to be discovered and Sovereign intends to control them all. Only the mysterious half-dragon Rake has a plan to stop Sovereign. To pull it off, he’s going to need a team.
