This is a bit different than the Percy Jackson series in a number of ways. First, this is not presented in first person. And that definitely makes sense as Riordan is no longer focusing solely on Percy as the protagonist of this series. Second, even though the world is the same, be prepared for a whole new slate of characters to be joining the world of Percy and the other Half-Bloods.

Overall, I really enjoyed it. It contains the spirit of the previous series, pulls in even more mythology and history, and delivers another great adventure with a few unexpected twists and turns.
