Katie Prager, the wife in the real "Fault in Our Stars" couple, died Thursday after complications from cystic fibrosis and a lung transplant.
Her husband, Dalton Prager, died just days earlier, on Saturday, after suffering from the same disease.
They were known as the real "Fault in Our Stars" couple, as their love story bore a resemblance to the 2012 book and 2014 movie "The Fault in Our Stars," in which teenage cancer patients fall in love.
