Okay people, I came across something interesting on Amazon.us
I don't know if anyone else has seen this, but apparently R.Riordan is doing another companion book, this time for the Heroes of Olympus series. The release date is currently set for August 14, 2012.
According to Amazon, the book will be called "The Heroes of Olympus: The Demigod Diaries". We can't be 100% sure that this is going to happen, as nothing has been confirmed by Rick Riordan yet. Amazon is a legitimate source though, so I for one believe that we are going to have this thing released.
Here is the book description from Amazon: What dangers do runaway demigods Luke and Thalia face on their way to Camp Half-Blood? Are Percy and Annabeth up to the task of rescuing stolen goods form a fire-breathing giant who doesn't take kindly to intruders? How exactly are Leo, Piper, and Jason supposed to find a runaway table, dodge a band of party-loving Maenads (who just might be a little psychotic), and stave off a massive explosion...all in one hour or less?
With his trademark wit and creativity, Rick Riordan answers these questions and more in three never-before-seen short stories that provide vital back-story to the Heroes of Olympus and Percy Jackson books. Original art, enlightening character interviews and illustrated profiles, puzzles, and a quiz to the fun in this action packed collection that is sure to delight legions of loyal fans.
Anyway, what do you guys think? Wouldn't it be cool to have a companion book for the Heroes of Olympus series?
