It is nothing like MIGHTY ATOM, it is very intense, with Lamp at his most evil!
I would not recommend it for young readers.
The story is 'good', though 'bad' at the same time; in other words, written well, but full of violence, meanness, & diminishing people's self-esteem.
While it is fiction, it is set during world war Two, and does give an idea of just how vile the Nazis, especially Gestapo agents really were.
