via press release:
TLC is premiering the mid-season finale of SISTER WIVES this Sunday, June 24 at 9/8c. Directly following at 10/9c, the network is premiering SISTER WIVES TELL ALL, a no holds barred interview where Kody Brown and the Sister Wives speak to NBC News' Natalie Morales about polygamy, life in Las Vegas, and their new book Becoming Sister Wives, which details life in the Brown family before the cameras started rolling.
The family opens up about how each wife came to the family, the difficult adjustments along the way, and the personality conflicts that nearly drove them apart. In addition, Natalie sits down with five of Brown's oldest children to speak candidly about life in this very unusual family.
