The Obsidian Blaze

After saving a human city from massacre at the blades of stitched-together, otherworldly monsters, Sia has been dragged back to her father's floating city. She can no longer hide from her magic, her family, or the seraph she's been bound to. However, the crown prince, Alezandral, has no interest in forcing her into their arranged marriage, so they strike a deal instead: he'll help her unravel the truth concerning her powers and she'll help him fool his country into believing their engagement is legitimate. At least until they can find a way to break the bond keeping them together. 

But these tasks may prove more burdensome than they anticipated.

The threat of war looms over their continent, seraphim are going missing, and the closer Sia gets to the truth, the more she learns about the powerful male at her side. As they work together to save their territories and each other, their bond grows stronger, the pull towards one another undeniable. Sia has spent her whole life fighting for her independence, but now that her heart is involved, she'll have to determine if freedom is what she truly wants.
