Sins of the Night

Danger is the first female dark-hunter that I know about. This is her story with Alexion who is Acheron's go to guy to fix things when dark hunters go bad. There is a war brewing within the dark hunters spurred on by Stryker and Alexion is sent to try to quell it. He meets Danger who doesn't quite know who to believe. Some of Acheron's past is revealed in this one. Loved it and need to read the next one soon.
