Dream to Me, by Megan Paasch

Still reeling from grief and feelings of guilt related to the recent death of her father, Eva and her half-sister Rhonda pull up stakes in New York and relocate to a small town in rural Washington.  Eva's great aunt bequeathed them the family mansion, which turns out to be an old house that is falling apart in the woods.  

The local residents want nothing to do with them.  Eva's people, it transpires, have long been rumored to be witches. It doesn't help things that, shortly after their arrival, people in town start falling into mysterious comas.  Suspicions circulate that Eva is casting hexes on the victims.  But while the comas are the work of magic, it is not Eva's doing.  Rather, as Eva learns, it is her destiny to rescue these people.  In order to do that, she must uncover a hidden history series of events in which she and her family played a major role.

A suspenseful, well-paced supernatural thriller with some significant things to say about guilt and addressing guilty feelings before they (literally, in this case) eat you up.  That balance between an engrossing story and some weighty advice about coping with guilt makes this a good read.  I won't claim to have followed every bit of the story and there isn't much character development, but I enjoyed the ride.  In sum a brisk and fun weekend read for people who enjoy non-gory horror.
