The Sweet Irony
It took me 6 pages to figure out why he didn't sound like Percy...it's in third person razz The PJO books were in first person. Lol, I fail.
Afterthought, though...I don't think I like this new Percy.
I know, I know. A lot of who a person is is who they know and what they do - their surroundings. And this Percy would have no memory of Sally, Grover or Chiron, so he'd be a bit different.
Maybe it's just me, but does anyone else find son-of-Neptune Percy more, er, negative? He's still got that ability to make near-death situations hilarious, but in his description of things around him he seems different. It's the same humor, but his words are uglier. One of the things I fell in love with in the first book was how Percy could be so angsty yet innocent.
