The Romulan Way
by Diane Duane alternates between the history of the Vulcan/Romulan schism and a story in the "present" about McCoy on Romulus. The "present" story is a sequel to Duane's earlier My Enemy, My Ally
and kinda requires you read that to understand the ending. Duane repeated the formula in Spock's World
, which combines the history of Vulcan with a story about the Vulcan people taking a vote on whether to leave the Federation.
Yeah it's fiction, but it's the closest I can think of to what you want. And the books are really good.
