The Mansions of Idumea (Book 3 Forest at the Edge series)
by Trish Mercer
Lt. Col. Shin isn't happy--about Guarders turning teens into thieves, nor about his children turning into teenagers. The whole world's shifting, with Mal tightening his control, yet no one except Perrin, Mahrree, and Shem seem to notice.
When disaster hits Idumea and his mother insists he return, Perrin's not sure what's worse: facing the government he hates, or taking his family along to Idumea.
