The Aether storms are getting worse, the tension is rising between Aria, as a former Dweller, and her newfound community of Tides--those humans who were not lucky enough to find shelter in the domed cities. Perry, Aria's lover and now the leader of his tribe of Tides, is losing his grip on the dissenting factions. Meanwhile, Aria and Perry haven't seen each other for months, and the time is quickly approaching for a desperate attempt to find the rumored Still Blue, the last haven on Earth.

Sequel to: Under the never sky.
