Retrograde Orbit - 1. Orbital Awakenings

Astronaut Eva Reyes awakens in space while her AI companion IAN explains he just saved her life by reversing her orbit without authorization. A solar storm has devastated Earth, all communications have failed, and she's possibly the only person alive in space. But then the stars start blinking in patterns that seem like... messages? When IAN detects an impossible signal from Madrid and the same stars that "speak" to her begin guiding her toward a landing that violates all laws of physics, Eva will realize that her sister Laura and a hacker named Damián are attempting something that could change the rules of the universe. Between outer space and an electricity-free Madrid, begins a story about impossible communication and the bond that transcends the laws of science.
