So, as you may know, I'm reading the Kane Chronicles, also by Rick Riordan. In the Throne of Fire, the second book, I found this quote.
"When Sadie and I first arrived at Brooklyn House, Amos had told us that magicians tried to stay out of Manhattan. He said Manhattan had other problems-- Whatever that meant. And sometimes when I looked across the water, I could swear I was seeing things. Sadie laughed about it, but once I thought I saw a flying horse."Ok, just think about this. HELLO!?! Blackjack, anyone? Flying horse? Manhattan (Olympus)? PUT TWO AND TWO TOGETHER PEEPS! :)
BTW, was anyone else thinking that a crossover series or book would be AMAZING?
