The House of Hades: 08/19/16
The House of Hades by Rick Riordan is the fourth of the Heroes of Olympus series. As this is now a larger ensemble cast, there are multiple adventures happening — all to the common goal of preventing Gaea from awakening.
At the start of the series Jason whisked away to Camp Half Blood with no memory of who he was or who he got there. Meanwhile, the camp's big damn hero, Percy, has gone missing. All of that has been resolved and now the members of the two camps must — to make the prophesy work — work together.
Much of The House of Hades is a dungeon crawl, well, through the underworld. No surprise there, right? As the focus was primarily on Percy and Annabeth finally getting to work together again, it was the part of the book I was most interested in.
