The ghost forest (secrets of the sky, book three)

The Kingdom Beyond is overrun with bhoot (ghosts who live in trees), and Kiya and Kinjal are the best hope of finding a solution. The ghosts are angry and dangerous-with one look they can steal your soul-so the twins must be extremely careful and use all their wits to help their flying horse friends and the rest of the inhabitants of the magical land so important to them. But what if the bhoot are angry for a reason? What if it's their very own home trees that are being cut down, leaving them with nowhere to go?

This time, Kiya and Kinjal face danger from even those they are trying to help. Can they find out who is destroying the ghost forest?
