Call of the Wilde (Immortal Vegas #8)

Hello darkness, my old friend...

Still recovering from an explosive family get-together, Tarot-reading mistress of the House of Swords Sara Wilde isn't ready to return to the war on magic. Then the Magician of the Arcana Council uses her to summon an ancient Greek deity for his own devious purposes, and Sara's suddenly up to her elbows in oversized egos and millennia-old conflicts. Conflicts that imperil the delicate balance of power between the most formidable mortals on earth and the gods who wait beyond the veil.

To keep both gods and monsters where they belong, Sara is forced to put out the first call to arms of the four Houses of Magic since the fall of Atlantis. Unfortunately, that call brings ancient enemies into the open and reveals truths about the Council--and the Magician himself--she would have preferred not to know. Worse, a brutal resurgence of violence rocks the Las Vegas Connected community and has Sara questioning everything she knows about her closest allies, while a nagging interest from Interpol evolves into a far more insidious threat. Sara's done her best to become a team player, but with friends like these...

Better pray it's a wrong number when you get the Call of the Wilde.
