Eva grew up in a climate apocalypse, her parents are dead, and the boy she once loved is probably trying to kill her. Just when she's about to give up, she discovers a new species born from plastic waste. More incredibly, she can mold these creatures into other beings — first a butterfly, then a fish, a deer, a bear — and eventually, a sister, Iris. As Eva dabbles with creating life, it becomes frightfully clear that her creations, Iris included, will either save humanity or end it.
As these unlikely sisters dabble at creating life, it becomes frightfully clear that Eva is dying of the wasting disease that has killed almost every human on the planet. When a dangerous boy from Eva’s past discovers the island, Eva must face an impossible choice — stop him before he destroys the paradise they have built or become like him to survive extinction.
