Reese can’t remember anything from the time between the accident and the day she woke up almost a month later. She only knows one thing: She’s different now. Across North America, flocks of birds hurl themselves into airplanes, causing at least a dozen to crash. Thousands of people die. Fearing terrorism, the United States government grounds all flights, and millions of travelers are stranded. Reese and her debate team partner and longtime crush David are in Arizona when it happens. Everyone knows the world will never be the same. On their drive home to San Francisco, along a stretch of empty highway at night in the middle of Nevada, a bird flies into their headlights. The car flips over. When they wake up in a military hospital, the doctor won’t tell them what happened, where they are—or how they’ve been miraculously healed. Things become even stranger when Reese returns home. San Francisco feels like a different place with police enforcing curfew, hazmat teams collecting dead birds, and a strange presence that seems to be following her. When Reese unexpectedly collides with the beautiful Amber Gray, her search for the truth is forced in an entirely new direction—and threatens to expose a vast global conspiracy that the government has worked for decades to keep secret.

I was born on Earth, not Kurra. I'm not human, even though I try to be. My people, the Imria, think I'm a little unusual because of that. They call me an Earthsider: as if I've crossed a line, chosen a side. Gone native. Before she met her girlfriend Reese, before she knew the role she would play in the fate of two worlds, Amber was a fifteen-year-old Imrian torn between two identities. Imrian by blood, Amber was forced to hide her true self to pass as human during the time she spent on earth. And even when she returns to Kurra, her human experiences, including first love and heartache, still separate her from her fellow Imrians. But when Amber undergoes kibila, a traditional Imrian coming-of-age ceremony during which Amber will choose her name and identity for the next fifteen years, she will be forced to either accept her role in both worlds or forge her own path. Malinda Lo's digital exclusive novella companion to Adaptation and Inheritance takes readers on a journey through Amber’s past, giving fans a glimpse into her life on Kurra and a deeper understanding of one of Adaptation’s most compelling characters.

Reese and David are different now. Surrounded by a web of conspiracies, Reece feels that she must choose between two worlds. Her choices: David - or Amber? This world - or another? Should they tell the truth, and risk everything?
