The Definitive C++ Book Guide and List : http://stackoverflow.com/questions/388242/the-definitive-c-b...
I like the breakdown of books by their goals in this FAQ : https://isocpp.org/wiki/faq/how-to-learn-cpp
I would say 'C++ Primer 5th Edition' and 'The C++ Programming Language 4th Edition' are good.
And of course, Effective Modern C++, although the other Effective series books from Meyers are a must read.
