–Austin after being freed from Nero in The Hidden Oracle.
Austin is among the campers that go to New York City and fight for the Olympians. He and his half-sister Kayla set traps along the Williamsburg Bridge, as commanded by their half-brother, Michael Yew.
Austin survived the battle, and was commanded by the new cabin counselor Will Solace, his half-brother, to look for Michael Yew. Michael's body was never found, though it is clarified in The House of Hades that he died in the Battle of Manhattan.
Austin appears along with Kayla, when Apollo is brought to Camp Half-Blood. When he learns that his father became mortal, he worries if that means the skills and powers they'd inherited from him shall disappear, Apollo assures him that they will not.
During music lessons he praised his father for his talent. He pairs with Kayla during the Three-Legged Death Race, during which they are taken hostage by Nero. Later, Apollo finds him and the other hostages tied to stakes and coated in flammable substances. Before the god-emperor sets him on fire Peaches attacks him and his father pulls him off the stake. Apollo gets him out and he tells him to free the others.
They fly back to camp as Nero's assault is taking place. Austin drives the chariot while Apollo shoots the plague arrow.
Apollo mentioned that Austin had told him he had to maintain his equipment while traveling.
After escaping the Strix, Apollo wonders how his son is doing at camp.
When Apollo and Meg return to camp after six months, Austin and Kayla argue with the harpies about eating new campers on the third warning rather then right away. The following morning he greets his father after returning from a walk with his siblings and tells him he wants to join him in defeating Nero during breakfast.
A couple of days later as the campers attack Nero's Tower, he takes his father from Kayla as his sister helps a group of campers against a Tauri Sylvestres. He takes Apollo to the residential area to find Meg. They run into Cassius, who apologizes for cutting off Lu’s hands, and the boy hands over Meg’s rings and his key card. The pair then move on. When the elevator opens they move down the hall and he stops Apollo as he takes out a mirror to inspect the surrounding area. He finds an empty library and a room full of sixty people waiting for the city to burn. Austin tells his father he has to cross the party to get to Meg and Austin creates a diversion and clears the room so that Apollo can proceed. After Nero is defeated, he and Kayla help out with the wounded and, as their father walks by, they give him a reassuring look.
Two weeks later, he and Kayla hug their father when he returns to Camp Half-Blood after becoming a god again.
Austin is a tall African-American boy, with cornrows shaped like a double helix. He wears a black wool peacoat and black jeans.
In The Hidden Oracle, Apollo describes him as looking about thirteen, along with "as if he'd stepped from the deck of an eighteenth-century whaling vessel."
Austin is a selfless boy who is willing to put himself in danger to help others.
