This young woman inspires with her cover of "Roar"

16 year old Olivia Wise has an inoperable brain tumor, and her physical condition is deteriorating. Hear her Roar, as she makes a dream come true by singing her favorite Katy Perry song.

She didn't have a lot of strength, or her full breath, but we think she did a wonderful job.
