Query: Amazing story! Brings WWII to life!

This telling of Iwo Jima kept me enthralled. It is the first book on actual events I have read about Iwo Jima. So much history I didn't know. I read many, many murder mystery books each year and none have produced nightmares - I had nightmares two nights in a row while reading this book. It's not for the faint of heart - but a touching, realistic story about brave men during WWII.
