Six girls go underground to save Manhattan

Ananke Fishbein, a normal 13-year old, narrates this charming adventure/mystery story set in New York City. When Ananke meets a new girl in her class, Kiki Strike, she knows something is up--Kiki's answer to 'what do you want to be when you grow up?" is "dangerous." And sure enough, Kiki has soon recruited six girls from different schools with very different skills to help her explore the hidden passageways beneath New York City. Can these clever girls gain control of their beloved and fascinating city? With little excerpts after the chapters such as "How to be a Master of Disguise" and a list of other underground cities/worlds, this is a book that captures the imagination regarding New York City as no book has done since Jack Finney's classic Time and Again.
