The Heroes of Olympus: The Demigod Diaries is set to be released August 14, 2012 and is the companion book to the one of the main series The Heroes of Olympus. Rick Riordan officially announced the book on January 9th, 2012 on his blog. His son, Haley Riordan has written a short story in the book.

"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 from 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 and The Olympians books. Original art, enlightening character interviews and illustrated profiles, puzzles, and a quiz add to the fun in this action-packed collection that is sure to delight legions of loyal fans."
