Taming Shadows - The Revelations Trilogy, #1

Four years ago, crime beat reporter Riley O'Rourke changed the world. To be fair, it wasn't entirely her fault. Tucson police headquarters was destroyed during a fight with a sorcerer, a vampire, and a giant. Footage of the fight went viral on the internet, and the existence of Preternaturals-vampires, witches, and other were-animals like Riley-was revealed. Not all the Preternaturals are happy with this new world order, however.
The Queen of the Winter Fae worries that exposing her hidden world will destroy it, and sends the nastiest storybook characters imaginable to kill Riley before she can out the Fair Folk, too. The Summer Queen promises to protect Riley if she does her a teeny-weeny favor. Riley agrees-what choice does she have? But dealing with the Fae is always a double-edged sword, and the Summer Queen neglected to explain that if Riley successfully pulls off the favor, the entire world might end up on the edge of destruction.
