Prisoners on the Zubalamo

In book 4 of the Colony Ship Zubalamo series, Mabel and Ian, the adventurers from Dome 17, are still learning about the strange things happening on the vast colony ship. They have some new friends, but everywhere they turn it feels like they are being restricted, limited, and controlled. The biomes are still mysterious, and strange, with many unknown things lurking in them. Is there any way to avoid being a prisoner on the Zubalamo?
