After he had finished his description to Rocco, Rocco stayed up all night and created the cover. Riordan told of how he had to describe to John Rocco, the book's cover artist, of what the book was about, because the cover had to be done before Rick had finished writing it. Percy is holding a Roman eagle standard, like those that the legions carried.

The cover has Percy Jackson on drift ice with a glacier in the background. Another excerpt that was read on a webcast event that aired on can be found here. On May 26, 2011, Riordan released both the cover art and the first chapter of the book confirming such speculation. It has led to speculation that the book would explore the events surrounding Percy and his involvement with Camp Jupiter, the Roman counterpart of Camp Half-Blood. By the end of the book he says that readers would have a good idea where the second book is going. The author hints that the answer would be revealed as Jason's quest progressed. In an interview by Scholastic with Rick Riordan for The Lost Hero, Riordan is questioned about the whereabouts of Percy Jackson.
