Dr. Anna Rykov is the main protagonist of the Utgarda Trilogy. From The Old Man’s Request: Book One of the Utgarda Trilogy, we learn that:

“Anna was born Tatyana Trevena, the sole daughter of poor Russian immigrants. In exchange for passage to Brooklyn, the sixteen-year-old was married to the much older, exiled Fyodor Rykov shortly after their arrival in America in 1912. Rykov was an old world man.

She completed her degree in three years and went on to pursue a doctorate.

But the Roaring Twenties was also a time of rebellion, when traditions were questioned in pursuit of new experiences.

Anna Rykov was player character from a Call of Cthulhu RPG campaign that I ran in the 1990’s. The original Anna was wealthy widow who had just completed her doctoral thesis. Her specialty was not defined, and she was not as strong or confident as portrayed in the novels.
