Eva has never been your typical teenager. She grew up in a climate apocalypse, her parents are dead, and the boy she once loved might be trying to kill her. Just when she’s about to give up hope, 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, and eventually, a sister, Iris.
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.
