While the first six books in Cabot's YA "Mediator" series were published by Simon Pulse and HarperTeen, this seventh title comes from Morrow Paperbacks and is classed as women's fiction. Because of Cabot's obvious crossover appeal? Or because heroine Suze Simon is starting her first job as guidance counselor at her old high school and preparing for marriage? Either way, Suze is still seeing ghosts.
