Ecosystems always exist in fragile balance, but imagine a planet that is sentient! On icy Petaybee, the planet itself seems to be orchestrating its own evolution—but the planet is also rich in exploitable resources, and the ruthless company, Integral, is poised to take advantage. Yana, an ex-company soldier with strong ties to the native Petaybeans—and the planet itself—tries to mediate with the company, but it isn't enough. The company needs solid evidence of the planet's sentience, so Yana and her friends have to find some other way to prove that the planet is more valuable to the company alive than dead. Power Lines, the second book in The Petaybee trilogy, is read by actress Marina Sirtis.
