Looking for fourth year Russian texts

[Romanov Artemi]

Dear colleagues,

A colleague of mine is looking for good textbooks (grammar & conversation)
that could be used in her fourth year Russian course. Her students are
already familiar with "Let's Talk About life", "Political Russian" and
"Ogonyok".

If you have experience with, or have heard of other texts for advanced
students, please, send me a message. Thanks,

Artemi Romanov
