Some years ago I read a german book. But it wasn't very good. Later I discovered LeanPub. There are very good books on average.
I didn't read them but there is a "Node Beginner Book" (in English and Português) and a more detailed "Hands-on Node.js" book.
But in general, I would say a good JS book (like "You don't know JS") is worth more than the best Node book. If you played the "learnyounode" course of NodeSchool, you should be ready for Node.
PS: If you want to use JS and C++ (or Rust ;) ) with Node, there is a book too.
