Query: A must-have book.

I am a professional C++ programmer, I develop in C++ and Object oriented Technologies from 1993.I am reading this book, just finished the 2nd chapter and I just wondering how many other secrets I missed till now.It's a surprise even for the veterans of C++. If you program in C++, you cannot miss that.(I will surely read even the following books of teh series, "More Effective C++" and "Effective STL")
