Texas girl, 18, who was born behind bars to attend prestigious Harvard in the fall

An 18-year-old girl who was born in prison, is set to attend Harvard University after graduating third in her class.

Despite facing adversity from the moment she entered this world, Sky Castner, from Texas, had the determination to propel her towards a brighter future.

Castner's journey began at Galveston County Jail, where she was born as her mother served her sentence.

However, her father, assuming the role of a single parent, took custody of her and raised her.

Castner penned her Harvard application letter, with the opening line boldly stating, "I was born in prison." which captured the attention of the university.

He said: "I was given a paper about her. Her hero was Rosa Parks, her favorite food was tacos from Dairy Queen and she loved to read. I thought this sounds like a bright little girl, I still have that paper today.

"She told me: "I've been to jail." I said: "No, that can’t be right'. I knew that I can’t just go eat lunch with this kid once a week, she needed more.", Hamby told the Houston Chronicle. '
