Through Moms Eyes Simple Wisdom From Mothers Who Raised Extraordinary Humans by Sheinelle Jones

Writing the book, Jones told PEOPLE in August, helped her learn things about her own mom.

“Even while I was writing this, there were times that were really tough and I would be writing a chapter with Lucille O’Neal, Shaq’s mom, and she talked about alcoholism, and I’m going through my own thing and I’m like, ‘You know what? She was able to push through that and motherhood didn’t stop,’” Jones said.

“And so I think you’ll find a thread at the end of this book. I hope it’s inspiring,” she added. “I hope people laugh a little bit. They may shed a tear or two, but ultimately it’s my love letter to moms.”
