"Demon's Bluff" by Kim Harrison

Hi fellow denizens,

Demon's Bluff by Kim Harrison
hardcover, 451 pages, $30, Ace. New York
Thankfully I got it at the San Francisco
Public Library Main in the New SF area.
        This is set in the Hollows as are
most of the tales in the endless (we hope)
saga of Rachel Morgan.  The world of the
Hollows is much like our own but Rachel
resides in Cincinati with a host of Vampires
both living and undead, some Weres, and
troublesome Elves, and  Demons who come
  in from the Ever-After  which in a previous
  volume Rachel with  some help recreated
  with power from ley lines.  She started as
  a witch but studied  and spelled hard and
  learned to twist  curses.  In this story she
  travels back  in time, but not alone but
   with an enemy.
  To retrieve a artifact she must solve a
  riddle from the maddest of demons.
  May be the culmination of the series.
        I enjoyed it very much despite my
  diminished capacity  for such.  Gotta
  work on eye evaluation appointment.
