The ninth book of this dark urban fantasy series follows necromancer Eric Carter through a world of vengeful gods and goddesses, mysterious murders, and restless ghosts. Eric Carter has a lot on his plate. He's hunting the Oracle of Las Vegas, a literal talking head that manipulates the future to make its prophecies come true. But it has a new trick. It can change the past, too. Now Jazz Age Los Angeles is invading the present.
Long gone buildings suddenly restored, decommissioned Red Car trains appearing on paved over tracks, miles of the city changing back to orange groves. Throw in a hundred-year-old doomsday cult, time magic, and a terrifyingly powerful spell to raise the dead and it makes for a busy week. Carter knows the Oracle is behind it all but he can't figure out how. Or why. But he better figure it out soon or he, the city, and everyone he knows might be wiped from existence.
Cult Classic is noir urban fantasy at its finest, with a cutting voice, sharp wit, and a plot that will keep you on the edge of your seat.
