Marshmallow reviews The Wrath of the Triple Goddess (Book 2 of Percy Jackson and the Olympians: The Senior Year Adventures) by Rick Riordan

The book bunnies have read and reviewed many books by Rick Riordan through the years. Today Marshmallow reviews a relatively new one: The Wrath of the Triple Goddess was published in September 2024 as the second book of Riordan’s new series: Percy Jackson and the Olympians: The Senior Year Adventures.

(Marshmallow had already reviewed the first book in the series, The Chalice of the Gods back in September 2023.)

Marshmallow’s Quick Take: If you liked Rick Riordan’s previous books, enjoy books based on Greek history and mythology, or just like reading fun books about family and friendship, then this is the book for you!

Marshmallow’s Summary (with Spoilers): Percy Jackson has had enough to worry about. As the son of Poseidon, his world is one of danger and death. Sure, he has an amazing family, awesome friends, and heroic adventures, but his senioritis is starting to get to him. As he approaches his graduation for New York City’s Alternative High School, Percy wants to apply to New Rome University, located in Camp Jupiter (the protective home of the Roman demigods, which was first introduced in The Lost Hero). Specifically, he wants to go to New Rome to be with his girlfriend Annabeth (a fellow demigod and the daughter of Athena) with whom he has shared many trials and tribulations. But in order to get into New Rome University, he has to get three letters of recommendation from three different Greek gods for completing quests for them.

In the first book of The Senior Year Adventures series, Percy got one from Ganymede, the cupbearer of the gods for retrieving the titular Chalice of the Gods. Now, he has been tasked with another quest, this time by Hecate the goddess of magic: he has to babysit her pet polecat Gale and hellhound Hecuba during the week of Halloween. Simple, right?

Percy accepts the assignment for two reasons. First, he’d probably end up as some unsavory type of animal if he didn’t, and, secondly, he needs that letter. So Percy, Annabeth, and Grover (Percy’s best friend who happens to be a satyr) stay over at Hecate’s house to complete this quest. But magical pets cause magical problems that need to be fixed … especially when Grover accidentally sets them loose in New York City. Can Percy and his friends find them before Hecate turns them all into candy corn?

Marshmallow’s Review: I really enjoyed reading this book! It gave me nostalgia for the original Percy Jackson series while simultaneously getting me hooked on this new one. I don’t always like add-on series for franchises—for example, I love the Harry Potter series, including many of the supplements like The Unofficial Ultimate Harry Potter Spellbook and The Unofficial Harry Potter Bestiary, but in retrospect, I didn’t like The Cursed Child quite as much. But—perhaps because the time jump is not as jarring—this book makes an excellent addition to the Percy Jackson world of Greek mythology and magical adventure. Rick Riordan clearly hasn’t lost his touch and his authentic writing voice that makes his books so amazing to read! I love the way The Wrath of the Triple Goddess jumps right back into his world, starting to further develop the characters and their lives.

Overall, there wasn’t a single part of the plot that made me sad or disappointed in this book. I can’t speak for all Rick Riordan book fans, but I found The Wrath of the Triple Goddess to be a really fun addition to the franchise and I didn’t find any flaws.

I should also note that while this book was really fun, it was also surprisingly nuanced. This is something I think Riordan excels at. He composes text that is extremely exciting and entertaining to read, but he also makes the reader think. I think Riordan is very sensitive and finds a way to make all of his characters have many dimensions. Even in the original series, all the heroes and—most admirably—villains are fully developed characters who have stories and backgrounds that have shaped them to be the way they are in the story. In this book, in particular, I thought that Riordan did a great job for Gale (the polecat), Hecuba (the hellhound), and Hecate (the goddess of magic). For example, Riordan introduces Gale as a comedic, farting pet but eventually peels back the layers to reveal the deep injustice of her past, her astounding strength, and her raw talent. Hecuba, who is set up as a dog who is hard to walk, is transformed into a tragic hero. And Hecate’s history is uncovered by Riordan, step by step. Riordan, I have noticed, has a remarkable ability to paint these Greek gods as powerful, immortal, incomprehensible beings, yet also simultaneously and unmistakably human. This level of nuance and depth is not as recognized as it should be, given the fact that Riordan accomplishes this in a children’s book while writing the funniest lines known to bunnykind. 

On a final note, the plot is fantastic! I am really excited for the third book of The Senior Year Adventures to come out. Riordan Wiki and Reddit claim the next book will be out some time in 2025 or 2026. I can’t wait to read it!
