This was one of the first sci-fi books I read as a kid. I loved it! It had me hooked for life on sci-fi.
I have been rereading most of Heinlein's juveniles this year,and have thoroughly enjoyed doing so.I certainly enjoy them more than his later stuff with there cringemaking trendy attitudes to sex and hright wing lectures on all sorts of topics.No time for all that tedious stuff when we are off gallivanting the universe having great adventures! lol
