Its a good book and a fantastic way to start of a new series, all the characters aren't introduced at once and it gives us time to understand their back story but I think that Jason is a bit to bland, the golden boy, leader, strong, blond and it is a bit of a stereotype and Piper's story line doesn't move along until the very last book in the series and its missing the greatest demigod, Percy, and of course Annabeth doesn't get to much of a role and then she suddenly gets a very big one, it is hard and not shown properly, and she is missing her boyfriend with his mom and dad.
