This Is Where I Want To Be

In modern America a teenage vampire/alien and four men's lives intersect into an ultimate reverse harem. Haunted by a past and a fascist ruler of her home planet, she battles her enemies to achieve her goal in life. To be happy.

Juliet is a strong female lead that has one outlook on life. To love what is good for her and to give all of herself to whoever wants to be a part of her life.
The supernatural aspect comes in that the origin of the creatures on earth is alien-based including vampires, werewolves, and others. They will be traveling to space.
There will be a lot of fighting, physically and emotionally, for what Juliet wants.
Ultimately, she rules the three planets and sets all the different species free of the bondages of their societies.
