No Reflections - Red Dragon, #1

Robin has always believed in magic, but she didn't used to believe in fairies or dragons or things that go bump in the night. Not really. Then she met one. Turns out, the old stories have a bit of truth to them, and getting the attention of the fairies is trouble. The kind of trouble that gets people killed or kidnapped, or eaten by vampires. When Robin's cousin and her best friend go missing, she has to decide if any of the fey who are suddenly interested in her for reasons they won't explain are trustworthy enough to ask for help.
Either way, a rescue is happening. Saving the world from a power-hungry magical psychopath is just a side quest.
