Deadwood by Karley Brenna

Auria Tenere has spent her life locked away in the castle she calls home and forced to serve her father, the king of Amosite. Clinging to bedtime stories of extinct fae and dragons in hiding, she believes there’s no hope of ever leaving the confines of the palace. That is, until her father arranges for her to be married to a stranger.
After being able to leave the chasm for the first time in her life with her betrothed, Auria’s group is soon attacked, leaving them no choice but to find shelter in the nearest town. But Deadwood isn’t all that it seems, and the tales she once thought were simply bedtime stories turn out to be more real than she ever could’ve imagined.
Faced with the lies she has been told her whole life, Auria is determined to unravel the secrets being kept by those in this outlaw town. Including those of the closed-off man she isn't certain she should let close—the one man her father seems scared of. From the moment she set foot in town, he’s had his sights set on her, and Auria wants to know why. But soon, being stranded with him isn't her only problem. Not when the king decides he wants his daughter back, no matter the cost.
