Ivan Southall was an award-winning Australian writer of young-adult fiction and non-fiction. He was the first and still the only Australian to win the Carnegie Medal for children's literature. His books include Hills End, Ash Road, Josh, and Let the Balloon Go. Also notable is Fly West, a book of true stories based on his experiences flying in Short Sunderland flying boats during the Second World War.
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.
Ok I guess. Didn't ever really grab my attention, and a book dealing with mine defusing should have you on the edge of your seat. I'd really like to give it two and a half stars. Felt too much like a dated story, not enough suspense.
