Jeff Langr and Tim Ottinger are collaborating once again to write for the Pragmatic Programmers. This time, it's not a deck of cards like Agile in a Flash--it's a book designed to help C++ programmers come up to speed on TDD (test-driven development). A related blog post goes into a bit more detail about the project. Look for announcements in the upcoming weeks if you're interested in helping review the book!
