I read this as an adult Teachers College student (part of a YA project) and found it informative, absorbing and, at times, exciting. If I'd known about disarming mines and bombs beforehand it'd be maybe not so interesting but I doubt that includes many readers. Also, I'm of the generation whose parents were actively involved in WW2, so events military were more relevant than for most young adults these days. On balance, Southall's Josh was more engaging than his Seventeen Seconds.
