Wicked King by Mary E. Twomey

Coming together wasn’t supposed to be this difficult.
Tensions run high when prejudices are brought to light in Drexdenberg. A harsh penalty for attacking the migrant shifters is instated, but that doesn’t mean Adeline and her family are safe from the bigoted assaults of the vampires. When she finds she can’t be quiet any longer over the exploitation of her people, all targets aim themselves at her, whether she’s ready for the abuse or not.
Ronin knows that keeping his relationship with Adeline a secret is the best move, but when the hatred of his people threatens to take her out, he realizes he cannot stand by quietly any longer. Fighting for her cause will only earn him more enemies, but when Adeline makes it clear that there’s no turning back, his fate is clear: Ronin’s love for Adeline might just cost him his country… or even his life.
