Aria is a teenager in the closed city of Riveri. Like all residents, she spends time with friends in virtual environments called Realms, and accessed through an eyepiece called Smart Eye. Aria uses Realms and leads an easy, thoughtful life. When she is kicked out of town for crimes she didn't commit, she believes her death is inevitable. The outside world knows how dangerous death is, and that it is almost everywhere. As an outsider, Perry has always known hunger, predators and violent storms of energy. An outcast even among his hunting tribes, Perry endures these trials every day with his exceptional abilities, because he is gifted with powerful sensitivity that allows him to smell danger, food and even human emotions. They come together reluctantly, because Aria must depend on Perry, whom She thinks he's a barbarian, but he can help her get back to Riveri, and Perry needs Aria to help solve the mystery of her beloved nephew's kidnapping. Together they go on a journey, challenge their prejudices, and encounter cannibals and wolves. But to their surprise, Aria and Perry begin to fall in love. This love is the one that will forever change the fate of all who live Beneath the unprecedented skies.
