I have to say this is best of the Trials of Apollo series so far. We’ve settle in nicely into Apollo/Lester’s to rescue the oracles from the Triumvirate and earn his place back on Olympus but the stacks are much higher than ever before. If I had one issue with Rick’s works is the lack of consequences for the main characters. The life of demigods are often faced with many deadly trials but somehow always managed to live. After a while, the near death experiences lose their impact when the reader knows the character is going to live because they are after all the hero. True as readers we want them to live and have their happy endings but you can’t keep stating how dangerous demigods lives are if they never truly see the consequences but I digress. Apollo and Meg explore the Burning Maze with the help of Grover. This leads them to California where the west has been dealing with unprecedented wildfires. Either Rick knew that California would dealing with wildfires in real life or just coincidence. It would be nice if a few demigods could go in a maze, defeat an enchantress and stop the wildfires but alas it doesn’t work that way. The maze brings them to Meg’s former home and the help of Piper and Jason. Our heroes face the third Emperor who is by far the most dangerous. More than anything, we are seeing the most growth in Apollo is this one. He’s still Apollo so the ego is still big but it has had some bruising. He’s starting to understand his own humanity as he’s understanding that he is no longer immortal and is truly vulnerable. Apollo is slowly embracing his humanity and with that comes all the joys and the pain that comes with it. More than anything, if he is going to complete his quest he is going to have to become more human and depend on his friends to do it. The stacks are much higher than they have ever been in one of Rick’s series and making of powerful series.
