Jinger Duggar Is 'Eager' to Read 'Brave' Sister Jill Duggar's Bombshell Memoir: She's 'Found Her Voice'

"I love and support my sister," Jinger Duggar Vuolo said of big sister Jill Duggar Dillard

Jinger Duggar Vuolo is singing her "brave" sister Jill Duggar Dillard's praises!

In a YouTube video uploaded to her channel on Wednesday, Jinger, 29, admitted she has not yet been able to read Jill's explosive debut memoir, Counting the Cost, which provides in-depth commentary about her upbringing within her controversial church and family. But Jinger — who also penned a book earlier this year about her experiences, titled Becoming Free Indeed — expressed excitement about getting to read it soon.

"I actually haven't read Jill's book yet, but I am eager to do so," Jinger said while recapping her time in New York City filming her appearance on Tamron Hall. "I was able to talk [on the show] about how I love and support my sister and I'm so glad that she has found her voice and is sharing her story now."

Later in the video, Jinger was shown picking up a copy of Jill's memoir at a local bookstore. She then noted that this was the "first time" she was "reading some little sections here in New York."

Jill's memoir debuted earlier this month. Ahead of the book's release, she told PEOPLE that she "didn't want to have to write this story" but felt "called to do this."

"I do love my parents. I love my siblings. I struggle with the weightiness of it. But I feel called to do this," she explained. "I feel passionate about empowering other people to find their voice, and if they do that through my story, great. I want them to feel like they're not alone."

"I know there will be nay-sayers, but I feel called to do this," she continued. "We really wanted to tell our story for my siblings, because some of them are going to face similar challenges, if they haven't already, to what I've faced."

The memoir came out months after Jill, 32, joined her husband Derick Dillard, cousin Amy (Duggar) King and her husband Dillon King, and dad Jim Bob Duggar's sister Deanna Jordan in speaking out against their family and controversial religion, the Institute in Basic Life Principles (IBLP), in Prime Video's Shiny Happy People: Duggar Family Secrets docuseries. Though Jinger opted not to appear in the four-part series, she previously told PEOPLE that she "had heard a little bit" about it from Jill and was "excited to hear what she has to say."

"I was actually approached and asked to participate in the docuseries, but I thought that from my perspective, I really wanted to make sure that I was able to share my story in my own words and in my own timing," Jinger said in June. "So that's why I wrote Becoming Free Indeed, was to share more of my journey out of IBLP's teachings. I wanted to be able to share it in a way that was, like, God-honoring and hopefully sharing my story in a balanced way."
