Pale Demon is the newest installment in The Hollows series by Kim Harrison. I have written about Harrison many times on this blog, and I am happy to give her books another plug as I have just finished Pale Demon and loved it.
Book Description: Banned from the flight lists, Rachel teams up with tycoon Trent Kalamack, headed for the West Coast for his own mysterious business. Can a witch, an elf, a living vampire, and a pixy in one car survive for over 2,300 miles? And that’s not counting the assassin on their tail.
