I really liked this book because it was action packed, and the idea of having a underworld under New York City is pretty cool. I thought this book was unique from other ghost stories, because the ghosts were allowed to go to the surface at night.
My favorite part was when they were getting chased for the final time. I liked it because they were floating over New York, then sailing on water, and the underworld guards were chasing them.
I thought Jack was the person that changed the most, he grew from soft to hard and didnít let anything stop him.
I recommend this book for ages 10-13.
