Power Lines - Anne Mccaffrey, Elizabeth Ann Scarborough

Power Lines is the second novel in the Petaybee Trilogy.

Petaybee is a sentient planet. Yana is convinced and so are most Intergal people and all of the natives. The trouble is not everyone thinks Petaybee is sentient or even a good sentient. Convinced is not proof and they need proof. Can Yana, Sean, and the rest find that proof before Intergal starts mining and destroys the planet? Very highly recommended.
