I continue to enjoy this series. Percy is a bit of a dolt though. I mean, Athena just gave him a warning, and then he does something-no spoilers-that directly falls into the warning. 
 I am intrigued by Luke. What is motivating him? I think it's what we see in many people-the need to be loved by those who are most important. 
 In general, the characters of the gods are weak. But, maybe their flat characatures are purposeful. I guess hats how I would have played it, too, Mr. Riordan. I just don't like it.
