I read the whole thing in one day. It was absorbing and transporting even though it was set in NJ/NY, where I currently live. I loved Ethan and Prenna's relationship, and the premise was wildly imaginative without being too far fetched. It read a bit younger than I expected it to, so I would recommend it to a preteen/tween crowd instead of a 15 or 16 year old. Still, a really great story though.
