"In the follow-up to Lightless and Supernova, C. A. Higgins again fuses science fiction, suspense, and drama to tell the story of a most unlikely heroine: Ananke, once a military spacecraft, now a sentient artificial intelligence. Ananke may have the powers of a god, but she is consumed by a very human longing: to know her creators. Now Ananke is on a quest to find companionship, understanding, and even love. She is accompanied by Althea, the engineer who created her, and whom she sees as her mother. And she is in search of her "father," Matthew, the programmer whose code gave her the spark of life. But Matthew is on a strange quest of his own, traveling the galaxy alongside Ivan, with whom he shares a deeply painful history. Ananke and her parents are racing toward an inevitable collision, with consequences as violent as the birth of the solar system itself--and as devastating as the discovery of love. Praise for C. A. Higgins's Lightless "[A] measured, lovely science-fiction debut. contained, disciplined, tense. The plot is compulsive. Lightless is the first of a planned series, and you can't help looking forward to learning what's next."--The New York Times "Absolutely brilliant. This is science fiction as it is meant to be done: scientific concepts wedded to and built upon human ideals."--Seanan McGuire, New York Times bestselling author of the October Daye series "The stakes in this story are high--life and death, rebellion and betrayal--and debut novelist Higgins continually ratchets up the tension. A suspenseful, emotional story that asks plenty of big questions about identity and freedom, this is a debut not to be missed."--Kirkus Reviews (starred review)"-- "Radiate explores the fate of Ivan, the mysterious revolutionary whose secrets lie at the heart of intergalactic revolution--and Ananke, the sentient spaceship who is learning what it means to be human"--
