War from both sides: who's right? who's wrong?

Lots of tough decision for characters to make in Bamboo People by Mitali Perkins.  Chiko is a quiet 15-year-old who dreams of becoming a teacher, when he is taken by force into the jungle to start training for the army of Burma (now Myanmar).  Life is brutal and miserable, but two thoughts keep him going: trying to find out about his father, who was arrested as a traitor, and the hope of once again seeing a girl whom he adores.  After Chiko is severely wounded by a land mine and on the verge of death, he's discovered by Tu Reh, a teenager on the opposing side of the war.  Tu Reh's house was destroyed by Burmese soldiers...what will he do to Chiko?  Half of the book is narrated by Chiko and half by Tu Reh, so the reader gets a fascinating glimpse into two Asian cultures and an idea of what life would be like as a child soldier.
