I'm trying to find the exact name of the author and the novel.
- I know the supposed Russian transliteration/translation of the novel/author.
- When I Google for the work, using my best guess at the original English author/title, I don't get anything useful.
- I don't know anything else about the work, but I do have a description of a Russian fantasy movie that was supposedly made “based on the novel”.
I ran into a description of a 1990s Russian movie called "Психодинамика колдовства" ("The psychodynamics of witchcraft").
According to the movie description, it is supposedly based on a novel by someone named James Gann, called “Wherever you are” (Russian text has ‘По повести Джеймса Ганна “Где бы ты ни был”').
When I Google for this "James Gann", I get nothing useful - mostly, LinkedIn profiles and such.
 the English translation is mine, and the most likely reason for the failure is the process of English-Russian-English translation, the final English version may have incorrect spelling or even wording. Although I don't rule out the movie info simply having incorrect fact.
I don't know anything about the work itself, except the info about this Russian movie made which was made “based on the work”. How closely it hews to the original novel is anyone's guess.

His human feelings conflict with the drive of a scientist… (English translation mine, Russian original below)
