American first sisters-turned-best-selling authors Jenna Bush Hager and Barbara Pierce Bush have a new children's book called Love Comes First in the works, and they're bringing it to Dallas for a special event before it's released to the public.

On Saturday, November 4, the authors will appear at an early-release celebration at the George W. Bush Presidential Center at SMU. It will be their only appearance in Dallas on a book tour that also includes Texas stops in Midland, Lubbock, and Waco (November 2-4); and a special event in their late grandparents' beloved Houston, at the Memorial Drive United Methodist Church, on November 5.

According to information from the Bush Center, the Dallas Love Comes First event will be a family-friendly affair that includes:

• An opportunity for guests to meet the sisters for a family photo and to receive a pre-signed book.
• Children’s activities and refreshments.
• Tours of the George W. Bush Presidential Museum's permanent exhibit and special exhibit.

(Note that the authors will not be personalizing books nor signing other memorabilia, organizers say.)

The event will run from 4-6 pm. Tickets are $10 for adults, plus $19.99 for a pre-signed copy of the book; free for children.

Love Comes First(Little, Brown Books for Young Readers, $19.99) officially goes on sale November 7.

Its description reads: "As two sisters watch their friends’ families grow, they wish on a star for a sibling of their own… and a younger brother and a baby cousin arrive! The new family members aren’t exactly what the sisters expected, but with time and patience, the group soon becomes fabulously four – and lets their imaginations soar! Together they can be anything, and no matter what, they will always remember that love comes first."

The book is inspired by Jenna and Barbara’s own families, the publisher says, and is a companion to their #1 New York Times bestseller Sisters First, "a tender story about the way our hearts can always make room for more."

It features illustrations by Ramona Kaulitzki, who also illustrated Sisters First.

Jenna Bush Hager and Barbara Pierce Bush, the twin daughters of President George W. Bush and Laura Bush, grew up in Dallas, where their parents now call home.

Jenna is a host of NBC’s TODAY with Hoda & Jenna and the founder of "TODAY’s Read with Jenna" book club. Barbara is cofounder of Global Health Corps, an organization that works to solve some of the world’s biggest global health challenges.

The women appear regularly as guest speakers at fundraising events in Dallas, but public events together are rare.

In an Instagram post, Jenna expressed excitement about going on a book tour with her "sissy" this fall.
