I think there are several Michael books out there that try to present the material to a wider audience by leaving out the less empirical aspects of the teachings, and focusing more on the things people can use no matter what their belief system is. So they're not going to talk about reincarnation, channeling, planes of existence, etc., but only the useful information about personalities and how to understand others.
I don't know if Tao to Earth and Earth to Tao, by Jose Stevens, ever made it into French translations, but I find those to be the most methodical and complete Michael books.
