Through the years, Marshmallow has reviewed quite a few books written by Rick Riordan. Today she revisits the world of Percy Jackson, a Greek demigod whose adventures we have read about in the Percy Jackson and the Olympians series, and his friends whom we met in the Heroes of Olympus series. In the review below, Marshmallow tells us her thoughts about The Demigod Diaries, published first in 2012, written after the completion of the first series and before the completion of the second.
(Marshmallow reviewed three books from the Percy Jackson and the Olympians series; check out her reviews of The Lightning Thief, The Sea of Monsters, and The Titan’s Curse. Caramel reviewed the graphic novel versions of the same three. See his reviews of The Lightning Thief, The Sea of Monsters, and The Titan’s Curse.)
(Marshmallow also reviewed all five books of the Heroes of Olympus series: The Lost Hero, The Son of Neptune, The Mark of Athena, The House of Hades, and The Blood of Olympus.)

Marshmallow’s Quick Take: If you liked some of the other books by Rick Riordan or enjoy books about Greek mythology, then this might be the book for you.
Marshmallow’s Summary: This book consists of a couple short stories placed in the Rick Riordan world, games about the Rick Riordan world, special pictures, and one interview with George and Martha, the snakes on Hermes’s caduceus. There are four short stories: “The Diary of Luke Castellan”, “Percy Jackson and the Staff of Hermes”, “Leo Valdez and the Quest for Buford”, and “Son of Magic”.
“The Diary of Luke Castellan” is written from the perspective of Luke Castellan, a major character in the Percy Jackson and the Olympians series. The story details how his friend Thalia found her shield (Aegis) and how they together met a seven-year-old Annabeth, one of the most important characters in the two series involving the Greek and Roman gods and goddesses.
“Percy Jackson and the Staff of Hermes” is written from the perspective of Percy Jackson. The story is about Percy Jackson’s mission to recover Hermes’s caduceus.

“Leo Valdez and the Quest for Buford” is about Leo Valdez’s search for Buford, his trusty table friend. We met Leo Valdez in The Lost Hero, the first book of the Heroes of Olympus series. Leo is a son of Hephaestus, a skilled mechanic, and a goofy but faithful friend.
“Son of Magic” concerns a half-blood who chose to side with Kronos during the Percy Jackson and the Olympians series. The half-blood is in trouble, being chased by a monster, and he needs the help of a mortal. This story was written by Riordan’s son Haley Riordan.
In addition to the four stories, the book contains an exclusive interview with George and Martha, the two snakes on the caduceus of Hermes. There are also some trivia games and a word search puzzle.
Finally, the book includes several full-color full-page illustrations of several of the main characters from the two series. In particular there are full-page images of Annabeth, Percy, Luke, Piper, and Leo, and some illustrations of specific places. The colored illustrations were made by Antonio Caparo and the black-and-white ones were by Steve James.

Marshmallow’s Review: I really enjoyed reading The Demigod Diaries. I think it makes a great addition to my Riordan collection, and it really explained some things that happened in the main books of the two series involving the Greek and Roman demigods. Some of the events in this book were mentioned by the main characters in the main series and it was good to have the full stories be told.
I enjoyed the games and thought that the images were really well-drawn. The stories fit right into the world that Rick Riordan created in his two main series, and it was nice to reconnect with the characters from them.
The Demigod Diaries does not involve the later series by Riordan such as the Trials of Apollo, Magnus Chase and the Gods of Asgard, or The Kane Chronicles. I haven’t read the Magnus Chase books or the Kane Chronicles yet, but this was fine; the stories in The Demigod Diaries take place before these other series, and so I think there are no spoilers.
Marshmallow’s Rating: 100%.
