Nico had warned them. Going through the House of Hades would stir the demigods’ worst memories. Their ghosts would become restless. Nico may actually become a ghost if he has to shadow-travel with Reyna and Coach Hedge one more time. But that might be better than the alternative: allowing someone else to die, as Hades foretold.
Jason’s ghost is his mother, who abandoned him when he was little. He may not know how he is going to prove himself as a leader, but he does know he will not break promises like she did. He will complete his line of the prophecy: To storm or fire the world must fall.
Reyna fears the ghosts of her ancestors, who radiate anger. But she can’t allow them to distract her from getting the Athena Parthenos back to Camp Half-Blood before war breaks out between the Romans and Greeks. Will she have enough strength to succeed, especially with a deadly hunter on her trail?
Leo fears that his plan won’t work, that his friends might interfere. But there is no other way. All of them know that one of the Seven must die in order to defeat Gaea, the Earth Mother.
Piper must learn to give herself over to fear. Only then will she be able to do her part at the end: utter a single word.
This book was, as usual per Rick Riordan, full of adventure and laugh-out-loud humor. However, the pace seemed kind of slow. There were two separate plot lines, and it took a long time for them to come together at the end. It was kind of jarring going back and forth between them because they were so different.
Riordan also introduced some new characters, but they didn’t stick around for long. That was disappointing. They did have a few battles though, which were cool.
It’s also sad that this is the last book in The Heroes of Olympus series; it’ll be hard to see these characters go. They’ve become friends.
