(written from a Production point of view)
- From the book jacket
- "I am Spock… I hold the rank of Commander in the Starfleet of the United Federation of Planets; I serve as First Officer of the Starship Enterprise. I am the son of two worlds. Of Earth, whose history is an open book… and of Vulcan, whose secrets have lain hidden beneath its burning sands… Until now…"..
- It is the twenty-third century. On the planet Vulcan, a crisis of unprecedented proportion has caused the convocation of the planet's ruling council – and summoned the USS Enterprise from halfway across the galaxy, to bring Vulcan's most famous son home in its hour of need.
- As Commander Spock, his father Sarek, and Captain James T. Kirk struggle to preserve Vulcan's future, the planet's innermost secrets are laid before us, from its beginnings millions of years ago to its savage prehistory, from merciless tribal warfare to medieval court intrigue, from the exploration of space to the the development of cthia – the ruling ethic of logic. And Spock – torn between his duty to Starfleet and the unbreakable ties that bind him to Vulcan – must find a way to reconcile both his own inner conflict and the external dilemma his planet faces… lest the Federation itself be ripped asunder.
The USS Enterprise is summoned to Vulcan to join the debates on secession. James Kirk, Spock, and Dr. Leonard McCoy are all called upon to present their arguments, as is Sarek, Spock's father. We also look into several episodes from Vulcan's past that deal with the development of modern Vulcan civilization and thought.
On Vulcan, a ruling group has voted to consider seceding from the Federation of Planets. This creates conflict for Spock and Sarek, who, if the movement succeeds, can choose to remain on Vulcan and break off all contact with Earth and the Federation, or stay on Earth but be cast out from their family and disgraced.
The main event that occurs is a referendum where Vulcan attempts to decide whether to secede from the United Federation of Planets. Political figures and dignitaries are invited to offer speeches to persuade the planet. Sarek has to speak on behalf of the government and state why Vulcan should leave. Sarek claims that it is not Earth that is a bad influence on Vulcan, it is Vulcan that is a bad influence on Earth. Sarek does not want Vulcan to secede, however, because then he would have to leave Vulcan with his wife, Lady Amanda. Kirk, Spock, and McCoy all speak on the behalf of the United Federation of Planets. McCoy proves to be a particularly good orator.
T'Pau, the respected Vulcan matriarch, is initially supportive of the secession movement. When she discovers that it was engineered by a vengeful T'Pring, however, T'Pau recants and on her deathbed makes Lady Amanda the new matriarch of the house.
In the end, Vulcan decides not to secede.

"Vulcan has no moon," various Vulcans have been heard to remark: accurate as always, when speaking scientifically. "Damn right it doesn't," at least one Terran has responded: "it has a nightmare."

"My name is Leonard Edward McCoy. […] I hold the rank of commander in the Starfleet of the United Federation of Planets my position is chief medical officer of the Starship Enterprise. And as regards the question of the secession of Vulcan, my position is, hell no!"
- - McCoy, addressing the secession debate
- This is the first Star Trek novel to be released in hardback.
- Author Diane Duane had been keen to further explore Vulcan history, having done so briefly in The Romulan Way. The central story line came about because "there had always seemed to me to be a certain tension between Vulcan and the Federation that was waiting to express itself in concrete terms. I just gave it a chance to do that." (Voyages of Imagination, p. 123)
- This novel is set after Star Trek: The Motion Picture. It includes a number of characters which recur in many of the novels of this era, including Harb Tanzer, and features Moira, a sentient computer on the Enterprise recreation deck.
- Sarek is stated to have attended the 2180 World Series, 138 years after the death of the event from DS9: "If Wishes Were Horses".
- In one of the "historic" chapters, the inner eyelid mentioned in "Operation -- Annihilate!" is mentioned. It is originally a genetic quirk that one of the tribes of Vulcans had developed living in the deep deserts. When that tribe attempts to take over the settlement surrounding Mount Seleya, their inner eyelid gives them the advantage over the other tribes, and they become the dominant tribe. Eventually, the genetic trait is distributed into the general population over time.
- The author's adaptation of the novel for the audiobook omits the "historic" Vulcan chapters and focuses solely on the contemporary story.
- The novel was reprinted in the UK by Pan Books.

The tentacles change color more or less constantly, and the bundle is topped off with a sheaf of pink-stalked and tentacled eyes with triangular pupils and a purplish, "bloodshot" look." When they speak, it sometimes seems to say things that don't seem to make much sense. The tone of their speech (and its content) could possibly be taken to suggest that they are somewhat prescient.
- The Sulamid were created by Diane Duane. A Sulamid also appears in a non-Star Trek book written by Diane Duane, The Wizard's Dilemma. Two Sulamids are seen drinking at Quark's in Worlds of Star Trek: Deep Space Nine, Volume Three: Ferenginar.
