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.

Harper Blaine has learned that there's more to reality than meets the eye. Dead for two minutes after being assaulted by an angry client, this small-time P.I. has discovered that she can see into and move around in the Grey, a mysterious paranormal reality that lives just below our own.

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)
