Living in a dystopic future, Leah and her younger sister Rachel are fighting to survive in a world thatÎs becoming increasingly unlivable. EarthÎs atmosphere has been poisoned by pollution, so each year the governmentÑTerraÑholds a contest for all eligible, healthy 16-year-olds. The winners, 100 teens who possess skills that will contribute to VenusÎs floating biosphere, are sent to the Floating City. Though both Leah and Rachel are talented gardeners, LeahÎs pollution-induced asthma makes her ineligible. After Rachel is selected for the Floating City, she tricks TerraÎs medical staff and sends Leah in her place to save LeahÎs life. Once on Venus, Leah continues to hide her true identity. She is assigned to work in the cityÎs greenhouse where she meets Rose, who awakens something inside her she never knew existed. But when LeahÎs asthma returns, sheÎs forced to find out whether true love can survive deceit, and if her sister's sacrifice was ultimately worth the price.
