Katie Gardner

Katie Gardner is a minor character in Percy Jackson and the Olympians.

The Last Olympian
Katie is the daughter of Demeter.

Katie is the counselor of the Demeter cabin. During the War Council Meeting, it is shown that she has had a bitter rivalry with the Stoll brothers, ever since they covered the whole grass roof of the Demeter cabin with chocolate Easter bunnies. She suggests that the spy is one of Luke Castellan's siblings (thinking it is most likely the Stolls). She is similar to her mother, Demeter, when she lectures. Once, she yelled at the Stoll brothers for wanting to steal things, which is ironic since they are Hermes' sons.

Katie rode on the strawberry trucks along with the rest of the campers from Camp Half-Blood to the Empire State Building, and prepared to defend the city. During the battle she was ordered by Percy Jackson to take her cabin and defend the Brooklyn-Battery Tunnel. It was said that they "turned it into a jungle." Later on when the fighting got closer to the Empire State Building, she was heard yelling to hold their lines. After the Battle of Manhattan, Katie reported to Percy when he came down from Olympus that she saw Rachel Elizabeth Dare leaving the Empire State Building unharmed, before taking Blackjack back to Camp Half-Blood.
