High atop Mount Olympus, as dawn breaks on a new academic term, normalcy returns to campus following a harrowing expedition into The Underworld to rescue kidnapped students. Zeus and his fellow Olympians now prepare to testify in The High Court where Hyperion will be tried for the attack on Crete and death of Anytos and Kronos will stand trial for the murder of MO Prep's Headmaster Ouranos. As the trial draws near, the MO Prep students and faculty are besieged repeatedly by a race of gargantuan stone and earth giants. Under heavy assault, the Olympians are forced to flee to the volcanic island of Limnos to regroup. Meanwhile, a toxic poison Zeus has carried with him since a prior fight with a dragoness creeps toward his brain. In a race against time and beasts, Zeus and his friends must find a way to survive not only the toxin ravaging Zeus' body, but also the giants who grow stronger after every attack, and somehow make it to the The High Court alive.
