CASSIA MORGAN (21), daughter of Veronika and Dr. Niles Morgan, plays an important role in Assurity. Like other young students in medical school, due to the lack of doctors or nurses, she is put on a ''fast track'' to her medical license. As a doctor, she joins her father in London as part of his team to search for the correlation he sees between ancient man's DNA and the aliens' DNA. Cassia strikes up a close friendship with her co-worker Prof. I'jaz Nehem but disagrees with both her father and I'jaz's line of research. Seeming to fight them all the way, eventually, her quick intellect allows her to enhance what they have uncovered and offers enlightened insight that leads to the cure for delirium.
