Ivy lives in the prison that used to be her neighborhood, until she finds herself selected for a new government experiment. ***** The Zoo is a place where all go to be Greater. Men and women and animals combine in the fight to be one with Mother Nature. All who are chosen are proud to serve the cause, no matter how things are outside their oasis. Everyone apart from Ivy either genuinely believes the lies or simply doesn't want to face reality. But one man knows the truth. They call him Keeper because that's what he's always been. He cares for the animals, serving their every need and following the rules to a fault. But the more time he spends with Ivy, the more he grows sick of the big lie. As rules are questioned, and walls are broken, they'll both need to decide which risks are worth taking.
