There is only a month left until the awakening of the goddess Gaia and her bloodthirsty children, and then the entire familiar world will be destroyed in a new war of gods and giants. Only seven heroes from the prophecy, led by Percy Jackson, can stop the goddess. But, alas, they have time left not a month, but only a few days, after which their friend will die at the hands of the giant twins. The heroes must make a difficult choice - go towards danger or, obeying a prophecy that promises them inevitable death, turn away from the path... The third book of the super series from the creator of the series about Percy Jackson, who has become one of the most popular literary characters of recent years!
