Plastic Girl. Plastic Girl, #1

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. "Maison has crafted an enigmatic, surreal SF castaway tale that ultimately pays off with a suspenseful account of a fight for survival.
An eerie and somewhat elusive SF tale that takes plastic recycling to a new level."- Kirkus Review
