In the 21st century, Irina wakes up and realizes she lived before, in 1807 and then, just as now, she could see the conscience of people. But the girl was hiding a dark secret. If she deemed unworthy of life those whose conscience she would pierce, she could not control her need to kill them. At the same time, Jonathan, over three centuries old, is trying to keep his blood thirst in check and has to make sure the girl remembers the events between 1807 and 1814, when her name was Ava Burke and was the daughter of Duke Henry Burke, the leader of the Order of Constantine. However, Jonathan, a draco, cannot simply tell her what happened and has to let her remember it by herself. As she keeps dreaming of a life long passed, her hunger for human life increases and the question arises if she will unlock all memories in time to destroy the Constantines?
The Order of Constantine, responsible for the curse, for the torture and creation of armies of dracos, thrives and its members are now some of the most influential people in the world. They do not use armies of dracos as they did in the 18th, 19th, and 20th centuries, but they control oil, diamonds and politics.
Mark, a man turned into a draco before the American Revolutionary War, was forced to fight for the British Lieutenant General Thomas Gage who used the ash of a white oak to control his army of dracos. Mark was tortured and would have been executed if Jonathan would not have saved his life.
Rene is the only living descendant of Amara, one of the four powerful witches that came in contact with the Order and then met their demise. After her sister was murdered by Constantines, she became a key instrument in the plan to destroy the Order.
The plan to make the Order perish depends on the four of them staying alive and unlocking all the pieces of the puzzle which started in 1807. But, the more of the mystery is uncovered, the more the body count grows and the more plans tend to go awry.
