Greywalker

Vanished

Plot

For Seattle investigator Harper Blaine, her own case may prove the most difficult to solve. Why did she--as opposed to others with near-death experiences--become a Greywalker? When she begins digging into her own past, she unearths some unpleasant truths about her father's early death as well as a mysterious puzzle. She sets out to find his ghost, but encounters only a void where he should be, leaving her with more unanswered questions.--From publisher's description.
