While I was looking around Amazon for a few things, I came across this:
While the picture on the cover makes for an epic billboard, it, sadly, doesn't look that great as a book cover (even if it does have Logan Lerman on it :P). The image was meant for bigger things than a paperback book, and it's a tad bit too movie-posterish, too hollywoodized for this. It feels as if the effect that the picture is supposed to have on you is getting suppressed. (Err...do I make any sense?) It does have many similarities to the original cover though: the back of Percy's head, who's in a body of water, facing an overcast New York City. Doesn't the title font look the same too?
