The premise of Denice Turner's new memoir Worthy is about being raised in a Mormon household in suburban Utah, trying to find her place in the Church.

In a couple of weeks, the country will celebrate Independence Day - the commemoration of freedom from British rule.

It commemorates the Emancipation Proclamation of 1862 and the nearly 3 year delayed notification to many former slaves that they were, in fact, free. It was a time when rebellious slave holders relocated their operations to more remote parts of the country, including the Southwest, so they could continue to practice slavery illegally. Tomorrow, a group of students and faculty at Northern Arizona University will host a Juneteenth celebration, and in this audio postcard they share with us what freedom means to them.
