The Amethyst Curse by Chantelle Thomson

Alexandria Taylor, Alex to most, lived the life of any average young adult since 1929 under the guise of a human. But it’s not always easy to live amongst your prey, as a vampire with animal instinct. Then one day, after 85 years living as one of the only vampires in the world, fate came knocking on her door, in the form of another vampire. Suddenly dragged into a world Alex never knew existed, she is forced to face the facts of her past that lead her to this life. Things only get worse when Alex stumbles upon a murder. But it’s no coincidence. After being framed and locked up for the murder, Alex must break out and find the real murderer before her captors find her. As she pieces together the clues, it becomes evident that she was a part of a much bigger plan.
