...The Night Tourist by Katherine Marsh. Yep, it is another School reading, but one I ended up enjoying even though I could only read a bit at night before I fell asleep, but that seems to be a recuring theme lately anyway.
Following review is from Bookbrowse.com what an interesting site!

From the Jacket Jack Perdu, a shy, ninth-grade Classics prodigy, lives with his father on the Yale University campus. Smart and introverted, Jack spends most of his time alone, his nose buried in a book. But when Jack suffers a near fatal accident, his life is forever changed. His father sends him to a mysterious doctor in New York City -- a place Jack hasn’t been since his mother died there eight years ago. While in the city, Jack meets Euri, a young girl who offers to show him the secrets of Grand Central Station, the secrets only true urban explorers know about. Fifteen flights below the train station, however, Jack discovers more than just hidden tracks and mysterious staircases. He has stumbled upon New York’s ghostly underworld, which may provide Jack with a chance to see his mother again. But as secrets about Euri’s past are revealed, so are the true reasons for Jack’s visit to the underworld. Masterfully told, The Night Tourist weaves together New York City’s secret history and its modern-day landscape to create a highly vivid ghost world, full of magical adventure and page-turning action.

Media Reviews BookBrowse If you're familiar with the Orpheus myth, you'll have a good gist of how the story will progress, but not without some unexpected twists and turns, and an ending that, despite the odds, manages to surprise. A couple of times, convenience for the sake of the storyline takes the place of credibility (would Jack's father really have let him travel to New York by himself, especially knowing what he did about Jack?); but such contrivances are few, and overall Marsh stays true to the essence of the original story while putting a modern and very witty spin on the timeless themes of love, loss and longing. Full Review (members only, 968 words).  Children's Literature This novel has an unusual situation, but it may be hard for older middle school or high school readers to be patient and stick with the story.  Publishers Weekly Starred Review. [T]his intelligent and self-assured debut will compel readers from its outset, and leave them satisfied as it explores universal themes of love, loss and closure.  Kirkus Reviews Teenagers knowledgeable about mythology and appreciative of sophisticated wordplay will especially enjoy this intricate read.  The Washingtonian - Whitney Spivey Although Marsh eloquently combines her interests in ancient Greece and historical New York, The Night Tourist lacks depth in the fantasy realm. The author spins a colorful tale of an extraordinary underworld, yet she often uses the supernatural context to facilitate events that merit more explanation. Too often, events fall into place a little too easily.
