A claustrophobic, literary dystopia set in the hot, luscious landscape of Andalusia from the author of The Golden Key.  After the ravages of global warming, this is place of deep jungles, strange animals, and new taxonomies. Social inequality has ravaged society, now divided into surface dwellers and people who live in the Upper Settlement, a ring perched at the edge of the planet's atmosphere. Within the surface dwellers, further divisions occur: the techies are old families, connected to the engineer tradition, builders of the Barrier, a huge wall that keeps the plastic-polluted Ocean away.  They possess a much higher status than the beanies, their servants. The novel opens after the Delivery Act has decreed all surface humans are 'equal'. Narrated by Pearl, a young techie with a thread of shuvani blood, she navigates the complex social hierarchies and monstrous, ever-changing landscape. But a radical attack close to home forces her to question what she knew about herself and the world around her.
