Nine Tailed Realm of Four Kingdoms Book 1 by Jayci Lee

An enemy on her tails, an innocent at her side, and a dangerous power within her that could destroy them all. Jayci Lee melds Korean folklore with modern Americana in this fiery new series.

Sunny Cho aspires to be the dullest, least interesting person in any given room, which can be challenging for a nine-tailed fox spirit. So she drifts from city to city—staying clear of any and all attachment—and keeps her fox buried deep inside her. It is better this way. She would rather live as half of herself than risk losing control of her terrible powers.

Ethan Lee, a friend she left behind eight years ago, is a brilliant and distractingly hot PI. When he tracks her down and asks her to help him find his brother’s murderer, Sunny knows her uneventful life is about to be turned upside down.

Traversing the mortal realm and the world of gods, Sunny and Ethan discover their quest is much more dire than mere vengeance, and their friendship might be…more. An ancient evil is stirring, and Sunny is faced with an impossible choice: save the worlds from annihilation or claim the love fated by the heavens.
