Patterson, a former advertising executive who coined such catchy phrases as "Nupe it!," knows how to entertain. His chapters are always short (some only two pages), and his writing is clear and unobtrusive; the reading experience is brisk--akin to watching a summer blockbuster. The book is not as dark or as weighty as the tales of detective-psychologist Alex Cross, but while some fans may be disappointed by Patterson's migration from pure suspense fiction, his first-person narrator Frannie, has a quirky realism that keeps this flight of fancy mostly on stable ground. --Patrick O'Kelley
