Next C++ book to read?

[toothyXdip]

I am finishing up reading "C++ Programming, 4th Edition: From Problem Analysis to Program Design" and I was wondering what the next book I should read is. I'm looking for a book that covers more advanced topics in C++ that are actually useful.

It's going to depend a LOT on what you learned from your book so far.
