I'm still reading People with a Purpose by Trevor Barnes about Teach Yourself books over the last 70 years. In total contrast I've also started reading Awakening by S J Bolton - whose Sacrifice I thought excellent some months ago.
People with a Purpose is brilliant for showing how ideas and attitudes have changed over the last 70 years. For example equal pay for equal work was just a pipe dream and considered a little stupid at that in the 1940s. On the other hand Teach Yourself Mothercraft stated quite plainly that bringing up children should be a joint effort involving both husband and wife which in the 1940s was perhaps ahead of its time.
Awakening is scary if you have a dislike of snakes. If you have a phobia then you'd be better not to read it at all. This author does suspense as well as anyone I've ever read. More when I've finished it.
