Symptoms of a Heart Break

Most 16-year-olds cause at least some damage on their path to adulthood. But Saira Sehgal has vowed to first do no harm. A girl genius, she's the youngest MD in America - and she hasn't picked an easy specialty: She's working on the cancer ward. Saira's always been good at getting what she wants, but she's new to adult challenges - like getting out from under the thumb of her doting mother, who works at the same hospital; like proving herself to coworkers who don't take her seriously; and crushing on a cute boy who happens to have stage-two leukemia. Turns out 'heartbreak' is one ailment Saira still doesn't know how to treat.
