The Lace Reader by Brunonia Barry

An American Gothic tale set in none other than modern day Salem, Massachusetts. Sophya (aka Towner) Whitney has run all the way to California to escape the family history. Although witchcraft abounds either in the modern form or the historical tradition of the town, no one can explain the disappearance of her favorite aunt. Family responsibility rather than any plan to solve the mystery through the family ability to "read the lace" is the reason for her return. But each answer she finds reveals more layers of family secrets to be explored. A perfect beach read.
