Heart of the Realms

Four unlikely non-humans get pulled from their home realms where they meet at a hotel. A hotel at the heart of the realms.
Lavinia, a demon from Hell, lonely, aloof, and desperate to escape her home.
Vixen, a part-fox shapeshifter from the Tribe, separated from her family and friends, loyal, loving, and fierce.
Cassius, a serious, lonely boy without powers living in a ghost realm of mist and darkness, without family, friends, or allies.
And Micah, the witty, sarcastic, imperfect angel, disliked and segregated from the rest of his kind for his flaws.
Together they have to unravel a complex series of mysteries that lead to a plot that could destroy the realms forever.
