Christian Reyna and Alejandra Rodriguez were born in the same city and grew up as childhood friends in Minnesota and later fell in love as teenagers.
Due to the strength of their love, they took a blood oath never to hurt each other in any way or love another person as long as they lived.
Unknown to them this oath would bind them, especially Alejandra to Christian for life.
Alejandra came from a long lineage of Vampires. Her dad was a Vampire and Mum was a human at the time they gave birth to her. (This was a rare occurrence), and that was why her nature had not revealed itself yet.
A few days to her eighteenth birthday, Alejandra and her family suddenly left for New Mexico because her powers would be revealed on that day.
They were both heartbroken at this development and tried to resist but couldn't
They never saw or were allowed to contact each other again.
As the years went by, humans became fully aware of the existence of Vampires and saw them as a threat, and sought them out so they could exterminate them.
This leads to a vampire revolt and causes a full-blown world war in which Christian and Alejandra are leading agents for their respective races.
As the war rages on, after almost ten years apart, Christian and Alejandra run into each other in the course of battle and Camilla can't bring herself to hurt him.
They eventually recognize each other and the fire of their love is rekindled once again.
They embark on a secret and forbidden love affair between Man and Vampire.
Jesse Clark, an equally high-ranking agent for the humans who is envious of Christian finds out and informs the humans about Christian's activities.
Diego De Paul a wicked and crooked vampire who Alejandra is betrothed to also catches Christian with her and reports her to the "Cardinals". The leaders of the vampires.
Christian and Alejandra are both warned and threatened but they do not heed the warnings.
They are excommunicated and hunted down by their respective sides amidst the ongoing war.
They then come together to expose both Diego and Jesse's plans to use the war for their own personal gains, while trying to stay alive.
They succeed in reconciling both sides and temporarily ending the war.
Christian eventually turns into a vampire as Alejandra has to bite him before he bleeds to death and they live happily ever after.
