Editorial Reviews

From School Library Journal

Grade 5–9—This slim volume is clearly intended as a stop-gap product to tide eager readers over until the final volume of the series is released. In addition to three previously unreleased short stories about Percy and his companions, it also includes such filler as interviews with the same, along with word games, portraits of some of the Gods and their half-blood offspring, and the inevitable sneak preview of Book 5. The short stories are the meat of this book, and are filled with Riordan's trademark anachronistic humor. The first one puts Percy and his enemy Clarisse, the daughter of Ares, on the same team as she tries to retrieve her father's chariot, which has been hijacked as a prank by her two immortal brothers. The second story relates an incident that occurred during one of Camp Half-Blood's infamous Capture the Flag games, when Charlie Beckendorf, the camp counselor for Hephaestus, is captured by a horde of giant, poisonous ants, and has to be rescued with the help of a mechanical dragon. The final story brings Percy, Thalia, and Nico, the son of Hades, together at the request of Persephone to help retrieve Hades's stolen sword, the loss of which could be deadly to the Gods, and the resolution of which forms a lead-up to the probable events of Book 5. Despite the fact that this is more of a marketing package than anything else, the quality of and interest in the three stories likely justifies its purchase.—Tim Wadham, St. Louis County Library, MO

Reviewed in the United States on May 7, 2009
Prologue and Disclaimer: Having read books 1-4 of the Percy Jackson and the Olympians series, with the final book 5 ( The Last Olympian (Percy Jackson & the Olympians, Book 5) , which I just received and am reading now, YAY!) on order, and being a completist at heart (yes, I also bought the Tales of Beetle the bard (both versions!  The Tales of Beedle the Bard, Collector's Edition (Offered Exclusively by Amazon)  and  The Tales of Beedle the Bard, Standard Edition ) and the Artemis Fowl Files  Artemis Fowl Files, The , I knew that I had to get this companion book for the Percy Jackson series as well. And since I also bought the other short story books, I knew going in that I'd be paying a premium for a hardcover book with less than 200 pages. But hey, it costs about as much as a ticket for a 2 hour movie, and lasted at least that long, so I'm not complaining!

So, the book comes with 3 short stories, a few 2-3 page "interviews", 8 color portraits of characters from the book, a crossword puzzle and a wordsearch puzzle, plus about one-third of chapter 1 of book 5.

Timelinewise, all 3 short stories occur between books 4 and 5, based on the age and knowledge of the characters involved.
The first story involves Clarissa and Percy (a unique pairing, compared with the other books). I liked the dynamic between the two, but wasn't crazy about the way Clarissa seemed so depending on Percy, instead of being able to carry her own weight more.
The second story was with Beckendorf (of Camp Haephestus) and Percy, later joined by Annabeth and Selina of Camp Aphrodite. Without going into too much detail, I wasn't crazy about the plausiblity of this story. I know, it's a fantasy book about greek gods, but the story had one of the characters reattach a mechanical head that was chewed off, back onto it's body, without tools, and get the robot working again, all in about an hour and a half.
The third short story was the best of the bunch, and seemed almost like a missing chapter of book 4, since the repercussions of that story may affect book 5 (I haven't finished book 5 yet, so I don't know if it will). The story revolves around Percy, Thalia, and Nico, so if you know about those characters, you definitely know the significance of those three to the storyline.

The interviews, color portraits, and puzzles were filler material, interesting to those who look for that stuff.

The excerpt of book 5, namely, the part of Chapter 1, was short but tantalizingly informative. A budding potential romance, a prelude to war, and a bag of greek fire, what more can you wish for?

I still have to say something about the price point for this book. The MSRP of this is a bit steep, even for a hardcover, when you compare it to the other companion/short story books (namely the Tales of Beetle the Bard and Artemis Fowl Files as comparison).

Overall, 4 out of 5 stars. I recommend buying it if you are a completist and need to read it before reading book 5 (like me).

UPDATE: 05/11/09
I've since read book 5 (
The Last Olympian (Percy Jackson & the Olympians, Book 5) ), and can unfortunately confirm that the final book makes no reference to the 3 short stories in this book. It's as if these short stories never existed. A shame, really, makes me have to think of the short stories as "what if" scenarios, as opposed to including them into the whole Percy Jackson timeline.

This is such a great extra book. A lot of insights of Camp Halfblood and three, once more amazing stories which fill in some gaps you might have when you read all the books. Fun little interviews, a map of CH, Percy's inner circle (explained by Percy himself = amazing), weapon guide, who's who and much more.
Gives the reader even more connection to the characters than he already has.
