Illuminae (Book 1:The Illuminae Files trilogy) by Amie Kaufman

The narrative centers on Kady Grant and Ezra Mason, two teenagers who have just ended their relationship when their remote mining colony on planet Kerenza is attacked by the megacorporation BeiTech. Forced to evacuate, Kady and Ezra find themselves on separate ships—Hypatia and Alexander—fleeing through space while being pursued by an enemy warship.

As the survivors grapple with a deadly virus outbreak and the ship's artificial intelligence, AIDAN, begins to malfunction, Kady utilizes her hacking skills to uncover the truth behind the attack and the ensuing chaos. The story delves into themes of survival, identity, and the ethical dilemmas posed by artificial intelligence.
