A deal between enemies. A curse that has no end. The love that brought the kingdom to its knees...

Eliza is the king's niece, but she does not at all like ceremonial receptions and lofty speeches. She befriends the servants and learns fencing, escaping from the castle at night.

Eliza's life ceases to be so serene when her uncle forces her to negotiate marriage. Unable to refuse the king, Eliza agrees to the care of Legion Gray, an attractive and mysterious young man dedicated to finding a good husband for the princess. But not only Eliza’s future, but also her heart is in his hands.

As the heroes get closer, their path becomes more and more dangerous. Enchanted people with black eyes attack the princess. The killer, more like a beast than a man, thirsts for blood. And the kingdom froze in anticipation of a fairy prince seeking to return the stolen crown.

A war between magicians and mortals is approaching, and Eliza must choose a side to protect the country...
