Y/N, chosen to represent North America, is taken aboard a joint human-alien research station where seven young people from Earth and seven from the Thaloryn ocean world have been selected from each continent to join a classified experiment. Among them are Zoe of Europe, Ethan of Africa, and Kaelith and Lysera, two Thaloryn chosen from their own planet. The truth is horrifying: each participant will be forcibly transformed, humans rewritten into alien bodies while the aliens are changed into humans, all to test whether two civilizations can survive in each other’s forms. In minutes, Y/N wakes with glowing skin, antennae, and three eyes, while Kaelith and Lysera awaken human. A second procedure is meant to rewrite their minds as well, but Y/N escapes before her human brain is erased. Trapped between species, she grows close to Kaelith as emotions awaken inside him, while Zoe slowly begins losing herself to alien perfection.
