Wow. A marvelous spin-off, I guess. :DD 
 So loving it to the height of Olympus! 
 Jason- He doesn't remind me that much of Percy(kind of), which, on my opinion, is good. :) He isn't impulsive, reckless, dense or sarcastic like Perseus Jackson. He's brave, smart, powerful-(view spoiler)[ who wouldn't, if you happen to be a son of Jupiter? (hide spoiler)] and handsome. I like him. :D 
 But while reading this, I experienced a li'l arguement going on inside my brain- My alter-ego was like, Watta heck! Where's Percy Jackson?! Don't just mentioning his name here!! 
 Damn, it was hard, knowing that I was beginning to contradict my other self for liking Jason. 
 Team Percy or Team Jason?! Wattafact?! 
 Piper-Gosh. Really, I'm so damn surprised to learn who the heck her godly parent, I mean, her mommy goddess is! Though my fondness of her character is only equal to Rachel Elizabeth Dare when she became the oracle, I like her charmspeak ability. It's so cool. 
 Leo-Oh, he's cute and very funny! I also think that he's going to be one of the most powerful among the seven demigods in the second Great Prophecy. 
 I also like the fact that there's another camp for demigods aside from Camp Half-Bloods. Now I can't wait to find out what's gonna happen between these two camps as the battle against Gaea and his ugly giant offsprings grew closer. And if Juno's plan to unite them is worth the sacrifice or simply a huge mistake. Most of all, I'm so eager to know these seven 'Heroes of Olympus'. Though I'm pretty much sure that (view spoiler)[Obviously they are: Percy, Annabeth, Jason, Piper, and Leo. While the second book, The Son of Neptune, introduces the remaining two, Frank and Hazel.
