When George wins an exciting contest from her favorite van life influencers to transport their camper van from Chicago to Los Angeles, she naturally invites Nancy and Bess along to live out her van life fantasies for seven days.

Could someone be trying to sabotage the trip? Or is Nancy so used to solving mysteries that she's starting to see villains where there are none?

Nancy had better figure it out quickly if their road trip--and their friendship--is going to survive the chaos.
