Kevin may write songs with his brothers, but he co-authors books with his wife too! In March 2022, Kevin and Danielle published a children’s picture book inspired by Alena and Valentina, whom he and Danielle welcomed in October 2016.
Titled There’s a Rock Concert in My Bedroom, the book highlights the power of music and family.
“Now our daughters, Alena and Valentina, enrich our lives in ways we could have never anticipated,” Kevin told PEOPLE in September 2021. “The love and care they show each other on a daily basis inspired this story and we are so proud to share how these girls not only uplift us and each other, but are creative, caring rock stars in their own right.”
