Once upon a time, a girl was born at dawn. Twenty years later, the girl wept for the downfall of dawn. Ilora Yang is a brilliant fourth-year surgical resident, best in her class and one of the most feared senior residents in Hartstone Medical Center. Jaylene Wu is a kid-loving, passionate, and cheerful resident in Ilora's year. Against all odds, Hartstone's most notorious bitch and sunshine girl find themselves becoming best friends, discovering each other's darkest secrets as they transition from nervous medical students to accomplished surgeons. Yet, with Ilora's abandoned past coming back to haunt her again and the arrival of a handsome, blue-eyed new surgeon, she finds herself needing her best friend more than ever. Perhaps even more than she could possibly imagine. "Dawn will rise again, brighter and more triumphant than before."
