The best things come in threes. So this Sunday, we're kicking off a new season with three back-to-back hours of "Super Soul Sunday" shows you won't want to miss.

At 11 a.m. ET/PT, watch the Oprah's Book Club interview with The Twelve Tribes of Hattie author Ayana Mathis. (This hour will also be streamed worldwide on Oprah.com and Facebook.com/SuperSoulSunday.) Before Oprah finished the first chapter of this author's debut novel she knew it was "the one." "It was an advance copy—the book hadn't yet been published," she has said. "Before I'd even finished the first chapter, I knew I'd found my second Oprah's Book Club 2.0 pick."

At 12 p.m. ET/PT, watch the premiere of In Deep Shift with Jonas Elrod, an unflinching look at people who were changed forever by an extraordinary event. Jonas—the filmmaker many "Super Soul Sunday" viewers will remember from his documentary, Wake Up—travels to Phoenix, Arizona, to meet Brian Mancini, a war veteran who is battling post-traumatic stress disorder as a result of a brain injury in combat. Along with Jonas, we'll see the different ways he has worked to heal his mind, body and soul.

At 1 p.m. ET/PT, Oprah and Rainn Wilson Present SoulPancake is a fun, thought-provoking hour dedicated to one of life's big questions: What is love, anyway? Whatever it is, this four-letter word is one of the most fundamental human experiences, and we'll find out how it affects us physically, how to sustain love and how to give it.
