McClintock's cohesive whodunnit carries the reader along in a snappy 223 pages. This is her genre and she knows her characters, plot, and action and where the story is headed. In this, the fifth book in the Robyn Hunter series, the eponymous "Robbie" has a substitute English teacher in her high school. This teacher just happens to be the daughter of Robbie's mother's boyfriend. Father and daughter have not seen each other since the daughter, Melissa, was eight, so the two are getting reacquainted. Melissa thinks she is being stalked by a man named Mikhail and is frightened for her life. Ted fears for Melissa and Robbie's father gets involved, too, as a private investigator. Meanwhile, Robbie is in a dilemma about whom she should love: Nick, the "bad" boy, or Ben, the super-rich-and-good-looking boy. I liked the book; it's safe for 6th grade and up to read. It's not edgy, murder is not graphically expressed, and the teens' language is unnaturally tame.
