Summary:
Ten years ago, Tony Stark died…

Only to survive as a vampire.

He owed his undead life to a vampire who turned him to save him. Being a vampire meant understanding his weakness to the sunlight, the poisonous touch of wood, and the possibility of developing super powers. It also meant accepting being isolated from all that he once knew and loved. As a young vampire, Tony spent his time avoiding V-Corps agents and staying near his coven. Looking for a taste of fresh human blood, Tony visited an illegal Blood Den where vampires and humans engaged in illicit desires. A willing human offered him a taste and Tony drank only to find out that his delightful salty sweet meal was none other than Captain America, aka Steve Rogers, a Captain for the V-Corps. When the tenuous peace between humans and vampire shatters again, not only is their forbidden love at risk, but their very lives.
