The Guicai Talisman. The Undercity Chronicles of Babylonia Jones, P.I.

What does a woman have to do to prove she belongs in the paranormal world called The Undercity?Sure, Babylonia Delilah Jones is unclassed and only half paranormal, but that doesn't mean she can't compete with the big bad boys and solve cases too. Since the established Private Investigators of The Undercity won't acknowledge her right to a territory, she's decided the only way to prove herself is to take the dangerous jobs from whoever is willing to hire her.
That means working for a witch to spy on Zaid, the Head of the Vampire House. Baby can hear flowers sing, can make grass grow under her feet, communicate with animals and the Wind treats her like an old friend, but nothing prepared her for the Guicai Talisman, or it's far too gorgeous guardian.
