The latest in the Percy Jackson Series cover revealed for the House Of Hades

The fourth book in the Heroes of Olympus series, The House of Hades, will be released October 8. 2013!  Sneak peeks will be revealed during the summer, as described above -- which is pretty much the same timetable Disney-Hyperion uses every year
looks like Percy/Annabeth survived their literal cliffhanger into Tartarus. ;~;
