Anna Dressed in Blood by Kendare Blake

This is a fun, quick read.  Its not gonna win any medals or awards but I recommend it all the same.
I think anyone who has heard the Chicago Ghost Urban Legend of Resurrection Mary would enjoy this.  Its the legend of the girl who was killed on prom night and still walks seeking a ride to prom?
She wasn't called Mary or Anna in my Iowa hometown where I first heard the tale.
This has a new spin.  Anna is trapped in a house where she viciously kills anyone who happens to enter.  Cas Lowood, a boy about the age of Anna when she died, is a ghost buster.  He and his white witch mom have come to town to release Anna and send her to where she belongs.  He has the knife his dad used before he died ghost busting.  Nothing much goes as planned.  People die, Cas loses his knife and Anna and Cas seemingly fall in love.  Anna is released but not to a final resting place, rather from that evil which trapped her in the house, perhaps the same evil that killed Cas' father?  Cas is possessed of an Obeahman requiring very special release using his mom, a kid and his grandfather who practice a bit of voodoo and black magic and some of the school kids who first introduced Cas to Anna and actually made it out of the house alive.  Anna, at first evil turns out to be quite likeable.  Cas lightens intense scenes with humorous statements.  And there is a sequel which I am about to read:  Girl of Nightmares.
