Frank was now in Alaska with Percy and Hazel, oh yeah, and Ella. He wasn't really paying attention to her quotes from the most random books, but his attention was grabbed when she said something about a demigod in Alaska.

The three Demigods were on a train, but all the carts were full. Frank saw a cart with only one person in it. He knocked on the door

"Excuse me? May we sit with you? There's no other empty carts." Frank asked politely.
