I have only read one other book by Alice Sebold, The Lovely Bones, and it was creepy - so is this one.
A woman crosses a line and then has to deal with the aftermath. In just a moment of unplanned action, her entire existence is altered. The book bounces back and forth between her childhood and the current time but it isn't difficult to follow or disorienting the way it can be in some books.
The book covers just over 24 hours of time but much occurs and many choices are made by the character that make you want to cringe.
This was a good book and I recommend it to anyone who likes her books and/or who likes psychological thrillers - it's a little on the disturbing side.
