Celine Dion has been such a consistent force in pop music for so long and was declared a legend so early ("My Heart Will Go On" from 1997's Titanic came out before Dion's 30th birthday) that it is easy to take her for granted. But her career and life have not been a straight up arrow, and she has known plenty of tragedy to go along with her run of triumphs. All the while, she remains a paragon of both generosity and personal integrity-with vocal gifts that will be treasured forever. There is only one Celine Dion, and this is her story.
