Morimoto, who now lives in Australia, describes the effect of the 1945 bombing on her childhood world. In clear, graceful prose and attractive illustrations, airy with white space, she portrays a happy family existence and her early pleasure in drawing and painting, and comments briefly on unpleasant changes when the war began--as a teen-ager, her summer holidays were spent ""doing military exercises."" Then, in a few succinct words extended by expressive, hauntingly authentic illustrations, this survivor presents the blast as she experienced it--""a thunderous flash and an explosion of sound. . .Everything faded away--I thought I was dying""; her home and everything around was on fire or destroyed; the dead and dying, in fire-shredded rags, were everywhere. The devastating contrast with Hiroshima as it was is pointed up by a large photo of the leveled city; additional photos on the endpapers, plus a color photo of the rebuilt city and a summary of facts, augment the information. A deeply mowing memorial and plea for peace.
