I think 'Acheron' is very popular. It has a very complex and interesting protagonist. His story is full of mystery and pain, which attracts a lot of readers.
Another good one is 'Dance with the Devil'. It follows the story of a particular Dark Hunter and his adventures. The characters are well - developed and the story is full of twists and turns. It shows the Dark Hunter world in a very vivid way.
Artemis remains alive in the Dark Hunter novels. She is a key figure in the series, with her own motives and powers. Her actions and decisions often impact the other characters, especially those related to the Dark Hunters. Although she faces various difficulties and conflicts, death is not her end in the story.
One of the main themes is the battle between good and evil. The Dark Hunters are often pitted against various dark forces. Another theme is redemption. Many characters have a past they are trying to atone for through their actions as Dark Hunters. And there is also the theme of loyalty, as they form a sort of community and have to be loyal to one another in their fight.
I'm not sure. Usually, you can check popular book platforms or literary forums to see if there's any buzz about new Dark Hunter novels. But as of the moment, I haven't caught wind of any.
One popular character is Kyrian of Thrace. He was once a mortal who had a difficult life and was then turned into a Dark Hunter. His journey of adapting to his new existence and his relationships are quite interesting. Also, there's Zarek, who is a bit of a rebel among the Dark Hunters, with his own set of problems and a troubled past that makes him stand out.
