Forced to take a vacation, Zion Police Chief Pilar Jones y Garcia joins Skip and his Far Trails crew on what she thinks is a random cargo run. Grumpy and short-tempered on the second anniversary of Garcia's death, she just wants to be left alone. Instead, she finds herself on a ship full of idealistic hippies, who are traveling to a hidden ecological preserve planet.

But sabotage on the ship and a murder on the colony derail Jones's hope of an uneventful vacation. And as she's exploring the wonders of the preserve's domed ecosystems, she discovers that the entire colony is in peril.

Can Jones solve two crimes, prevent a catastrophe, and find her missing inner calm?
