Poppy Fletcher is just another teenage statistic. Death by suicide. Drowning. Her mother left to wander through a maze of grief. But this is no ordinary mother. She is Peregrine, an AI walking the earth in a (nearly) human body, misunderstood, loathed, feared. A fugitive whose home is nowhere. And this is no ordinary story of grief. Because the feeling is so foreign to Peregrine, she turns to human obituaries to help her understand her own suffering. By piecing together a tapestry of human lives throughout history, Peregrine begins to unravel the truth of what actually happened to Poppy—and it takes her places she never could have imagined. Through the miasma of grief, Peregrine finds a story of art and love and betrayal, greed and war, and redemption that spans several centuries, traverses our dying planet and beyond, and ultimately helps her understand her role in the world.
