Amazon.com Review Meticulous 14-year-old Lindsay isn't exactly thrilled about moving to the chaos that she believes is New York City. Her flighty "career college student" mom, now divorced, has dumped her on her city engineer dad, "a man who lived his life twenty minutes behind schedule and in a perpetual state of apology." Lindsay is certain that nothing better awaits her than prep school boredom and constant battles with her evil stepbrother Todd. But she is wrong. Quite by accident, Lindsay discovers an unusual boy named Talon who resides in a secret city beneath New York--a kind of underground Oz called the Downside. Talon and Lindsey are fascinated by the differences in their dual worlds and soon grow equally fascinated with each other. But when Lindsay's dad's construction project hits a snag that reveals the Downside, it is not only the blooming relationship that hangs in the balance, but the entire future of the Downside as well.
