New Life (A Grey's Anatomy fan fiction)

What if Cristina Yang knew she had a sister but didn't tell anyone, not even Meredith? Kyleigh Yang is a brilliant Cardiothoracic surgeon who is just like her older sister Cristina who lives in Seattle. What happens when Kyleigh decides to leave the hospital she is at now and move to Seattle to work at Grey-Sloan Memorial Hospital to get to know Cristina?
