Simple yet poignant. This fairly short book (read in 35 minutes) quietly builds the case for peace through the loss of one hopeful, reflective young girl without being preachy or heavy-handed. Deaths caused by US nuclear weapons in war are difficult subjects to broach with young children. This book is age appropriate for grade 3-5, if handled well with an adult.

The source information and illustrated instructions of how to fold your own paper crane are helpful addendums.
