Vampire's Hostage

Holly is your average highschool student. That is, until one night she is partying with her friends in the woods and they recive a little suprise. No one had expected that a coven of vampires would discover them and take them hostage as measly human feeders.
Holly is the lucky one though, because the vampire that chose her was a prince. The Prince. The son of the king of all vampires. Unlike when a regular vampire were to bite, the prince's venom feels good to humans, letting holly not slowly die, but actually strengthen.
When she finally realises this, everyone she knows who was captured is almost on the brink of death, but will she still be able to save them?
and what if she's fallen in love? Will she even want to escape?
