Blood Empire Reborn - Luke Irontree & The Last Vampire War, #4

Luke Irontree was born in Belgium. If the vampires have their way, he'll die there, too. When an ally calls for aid, Luke and his werewolf friends must respond. Vampires are attacking his friend's pack, and they suspect treachery from within. As soon as Luke and his crew land, the vampires strike, kidnapping his friend. Luke is forced to go underground, relying on the protections of an ancient god. Now Luke and his team are on the run, eight people in a sea of enemies and allies with unknown loyalties.
They have no idea who to trust. Hunted across multiple countries, Luke is left with nothing but desperate choices if he wants to make it out alive.
