Is lee child the affair suitable for young adult or teen reads?

That is really going to depend on the individual reading the book. There are some very mature teens who are able to handle books above their reading level, there are others who might not be ready for such books, especially considering that "teens" start at age 13 and span through 19. That's a wide range of ages and maturity levels. If you have questions about the suitability of a book, talk to a librarian or teacher who knows the teen in question and would be able to answer specifically for that person.
