Summer is sweet as far as Careers go. She isn't vicious or bloodthirsty, but she will kill if necessary. Also, Summer is quite the tomboy, but she does have some degree of interest in fashion. That being said, Summer is very self-conscious.
Summer has long blond hair that naturally curls. She is strong and fast. Summer is 5'7 and always wears a silver headband and a red rose in her hair. Also, Summer has sweet glimmering blue eyes, and she wears purple eye shadow and pale pink lipstick.
Here is an excerpt from Summer's life twenty years after the Games:
I looked down at my twin baby boys and smiled. "Those two cuties are going to be fierce tributes in the arena!" said my husband, Darrel. Darrel was a victor too. He won 4 years before I did and he was the only one who understood me and what I went through. "I think we'll keep them out of the arena." I said. Darell nodded reasurringly. I was never going to let my kids enter the games. They were too traumatic to go through. At night, I still had visions of the tributes I killed. Darrel helped me through the nightmares, and I don't know what I would do without him. It was bedtime for the kids and I walked into their room and set them down in their crib. "Good Night Callam and Lou!"
During The Vengeance Games, Summer Ashton mentored the tributes of District 1 and also the tributes of District 10 along with Hex Servirior. Summer was happy about Copper and Amber being revived as she thought they stood the best chance of winning.
