Ebook: C++ Strategies and Tactics

If you are confused about templates or about the design of class hierarchies this place is a very good place to start.
The writing is rather compact and to the point and avoids the trap of getting the reader into a long boring example.
Yes sure, it's dated, (this book was written before STL came on the scene, but many of its ideas are there) but you may not need all the latest features of C++ right now. You should ease your self into C++.
It's a little more advanced than an introduction but it won't weigh you down, and hey the book is light enough that you can read it in bed.
It's a testimony to the idea that a well designed object has a very long lifespan.
