Lyssa grows up without a father, and this is something she struggles with. Her mother is a single mom who works a lot. Lyssa often resents her mother for not being home as much as she needs her to be. Most of the other kids in the neighborhood have stay-at-home mothers. Abbey is one of those kids, though she would prefer her mother be gone for most of the day. Abbey doesn’t always meet her mother’s high standards, which is a struggle for her.
The girls discover a Hideout in a remote area near train tracks, and much of their summer days are spent there. The girls embark on many endeavors at the Hideout, but placing pennies on the tracks and watching trains smash them is Lyssa’s favorite activity.
