In a near future when life is harsh outside of Earth's last unpolluted place, Cee tries to leave an abandoned island while her sister, STEM prodigy Kasey, seeks escape from the science and home she once trusted. It's been three years since Cee woke up on the shore of an abandoned island, with no memories of life prior, or how she got there. All she knows is she has a sister-- and is determined to find her. A world away, STEM prodigy Kasey is looking to escape from an eco-city-- meant to be a sanctuary but now populated by people willing to do anything for refuge. After a series of man-made disasters rock the planet, Kasey must decide if she trusts science to help humanity. -- adapted from jacket
