Takeaway: The Hero is often the hero in a way that they do not anticipate.
Percy Jackson, in the last book of the series, is sure he is the one of the prophecy. He is going to have to save Olympus and defeat Kronos. So when debates undertaking a dangerous task to prepare himself.
Of course there is always a problem with his love life (since Hera cursed him).
This book was much more battle focused than the others. That makes sense since it is the final battle that the whole series has been moving toward. While the battles individually are written well and do not drag, there are a lot of them one after another, after another. But they make sense in sequence and make sense at the end of the book. I am not sure any of them could have been left out.
Percy does verge on the almost too perfect hero problem. But there is just enough vulnerability to make him likable and to make sure there is tension in the book.
The ending does not feel like the end of a series. It is open so that more books can be written later. This story arc is done and wrapped up. But I would not be surprised if there are future story arcs. Overall a great series.
This book (and the series) is lendable in the kindle format. If you have a kindle or kindle app, you can put a comment below if you would like to borrow the book.
