Thrace and the Centaur: The River Styx

Thrace and Parker train all summer in preparation for Aphrodite's call. But the arrival of a bloody and beaten Battus requesting help from the son of Ares alters their path. Thrace and Parker, without the help of Sophos, who is not to be found, begin a new journey on their own.
On the battlefield, friends are reunited, new strengths are revealed, and death and prophecy are once again before the heroes. The return of Sophos brings anger and doubt between friends. But, when Sophos reveals his quest to enter the realm of Hades to save his father, Peirithous, friends come together for answers and understanding. For the journey to the Underworld will bring new challenges, new immortals, and test them, especially Thrace, far greater than any summer training can prepare him.
