An appealing debut, Greywalker has an opinionated, stubborn and likable heroine and a plot that clicks along with nary a hitch. While some of Harper's explanations of her new reality are confusing, they make perfect sense as she tries to reshape her world.
Dragged into the world against her will, Harper navigates it safely, aided by her friends Ben and Mara. She slowly overcomes her fear of the Grey and what it represents, while taking on new otherworldly clients. (Roc, Oct., 352 pp., $14.00)
