Twenty years after tragedy tore them apart, four sorority sisters still can't say no to sweet Mary Blake Bulloch. Reeling from a public divorce, Mary Blake rallies the group to complete a long-ago road trip cut short by scandal, betrayal, and the death of a Texas oilman's son.

Time hasn't healed all wounds. Helen's hiding a crumbling marriage. Charlie's haunted by a deathbed promise. Annesley's harboring life-changing news. And Lisa knows her decades-long silence about what really happened that fateful night could cost her everything-and everyone.

As the women pick up where they left off, old alliances shift and long-buried memories surface. What started as a reunion becomes a reckoning, forcing each woman to decide what matters more: the comfort of silence or the brutal cost of truth.

The Last Road Trip is a masterfully layered novel about the transformative power of friendship-and the bad decisions that get in the way.
