Recommendations for a good intermediate C++ book

[Panam 87]

Dear forum members,

I'm looking for recommendations on a good intermediate level C++ book.
I've read many that I liked (e.g. The C++ Complete Reference by Kyle Loudon) but I'd like something a little bit more advanced.
What are your go-to books/references to sharpen your C++ skills?

Thanks,
