In a world where the Greek gods are real, the legends about them must be real as well. And what were the Greek gods best known for? Two things: defeating the Titans, and coming down to Earth to have demigod children. Rick Riordan’s Heroes of Olympus series sees an old favourite hero—Percy Jackson, the demigod son of Poseidon—team up with some friends, some enemies, and some complete strangers to defeat a colossal threat to his way of life. Oh, and he’s the hero of prophecy too, a prophecy that spells doom for the world if he doesn’t stand up and join the fight. No biggie, right?

So, you have a son of Poseidon, daughter of Athena, son of Hephaestus, and daughter of Aphrodite team up with a son of Jupiter, son of Mars, and daughter of Pluto. A highly potent team, but an explosive one as well.  The House of Hades is the name of the fourth book in the series as well as the location of most of the action. The previous book ends at a tantalizing cliff-hanger, leaving you itching to get your hands on the next book. So, when The House of Hades came out, your only desire was to grab it and devour it page-by-page in a single sitting.  But, for that to happen, the book must carry on the tempo the previous book was left on. There is nothing worse than a disappointing sequel to a gripping book. The House of Hades does a fabulous job here, dropping you right in the middle of an airborne battle aboard the flying ship Argo II. As soon as you start reading you are caught up in the web of magic, gods and danger. The book effortlessly weaves that world and superimposes it on the world we know—so much so that you even begin to question whether gods and ...
