Star Trek: Vulcan's Soul

A trilogy of books in the so-called Star Trek Novel Verse, building upon the earlier novel Star Trek: Vulcans Heart and continuing the story of Spock and Saavik into the late 24th century. The trilogy also serves to bridge the gap between portrayals of Romulan-Federation political relations at the end of Star Trek: Deep Space Nine and the state of affairs in Star Trek Nemesis. It also sets up many of the players for the first book in the Star Trek: Titan series.

The three books are Exodus, Exiles and Epiphany.

The plot is divided between two time periods - the late 24th century, in which a mysterious race known as the Watraii are attacking the Romulan Star Empire without provocation, and the distant past following a family of Vulcans on the long exodus to Romulus.

This series contains examples of:

 * A Father to His Men: Female example. Charvanek, as ever, is a mother to her underlings, though since moving away from active service "her men" are her aids and staff rather than actual warriors.
 * Alien Arts Are Appreciated: Charvanek's office features Irlani art as well as Romulan.
 * Arc Welding: This trilogy links Star Trek: Vulcans Heart to Star Trek: Titan and Star Trek Nemesis. It also connects nicely with the Star Trek Deep Space Nine relaunch and the Star Trek: A Time to... series. In particular, it takes the political situation with the Romulans following the end of Deep Space Nine (namely, their alliance with the Federation and Neral being praetor) and alters it appropriately to set up Nemesis, in which the Romulans are isolationist again and the praetor is Hiren.
 * Arranged Marriage: As with many Vulcans, Karatek and T'Vysse were betrothed at a young age. They are Happily Married, as Vulcans consider arranged unions entirely logical, and rarely feel imposed upon.
 * Ass in Ambassador: Romulan Ambassador T'Kala is fond of posturing rather than negotiating diplomatically.
 * Big Badass Bird of Prey: The Mogai, after which a class of Romulan Warbird is named. And then there's the Shavokh, which is native to Vulcan. Karatek's ship in the refugee arc is named after it, possibly hinting at the origins of the Romulan tradition of bird-like vessels.
 * Bittersweet Ending:.
 * Blood Oath: The Watraii swore to avenge themselves on "the murderer race", and thus dedicated their entire culture to blood feud with the Romulans. For their part, the Romulans weren't even aware the Watraii existed.
 * Book End: Karatek's journey begins and ends with a Sundweller flying overhead.
 * Brains and Brawn: Rehaek and Torath are definitely such a pair, this time round.
 * The Caligula: T'Rehu.
 * Continuity Nod: Many. Just as an example, Scotty reads up on reports from the Corps of Engineers, and finds an interesting one about the starship da Vinci and a planet in a box. This is a Continuity Nod to the Starfleet Corps of Engineers story Small World.
 * Cosmic Horror: The Intellivore, a "living world" that drains the mind energy of its victims, and disguises itself as a habitable planet to lure in starship crews. A Continuity Nod to another book.
 * Create Your Own Villain:
 * Crossing the Desert: Surak, Karatek and their party, in the first book. It wouldn't be a Vulcan story without a grueling trek across The Forge.
 * Deep-Cover Agent: A crewman aboard the Alliance is in fact a Romulan spy, whose real personality has been voluntarily repressed until a pre-determined trigger re-awakens it. She doesn't do much; she’s there to report on Starfleet’s activities, not to sabotage.
 * Doomed by Canon: Hiren is praetor as of Star Trek Nemesis, meaning Neral's reign is doomed. Indeed, he's deposed in the final book of the trilogy.
 * Emergency Transformation: The extremophile life-forms of Remus alter Refas' physiology to help him survive, after he walks out onto the ice. They bond with him symbiotically to save him, mutating him into what will become the first of the Remans.
 * Emotions vs. Stoicism: It is a Vulcan-Romulan story, after all.
 * Endless Daytime: One side of the planet Remus.
 * Face Death with Dignity: Neral, who makes a deliberate choice to do so when Hiren has him assassinated.
 * Fantastic Honorifics: "T'Kehr", a Vulcan honorific for learned scientists or philosophers in positions of leadership.
 * Fantastic Racism: The various Vulcanoid races really need to learn to get along nicely. Luckily, they have Spock working on it.
 * Fire-Forged Friends: Frequent in the Vulcan refugee plot.
 * Fire, Ice, Lightning: Sarissa's journey. Vulcan (fire), Remus (Ice), Watraii homeworld (lightning).
 * Flanderization: Some accuse these books of flanderizing the relationship between President Zife and Koll Azernal, with Zife being an ineffective president relying on scheming Azernal to run the government for him. It is certainly more obvious in this trilogy than in Star Trek: A Time to.... The Brains and Brawn partnership of Rehaek and Torath is arguably flanderized, too.
 * God Save Us From the Queen: The Ruling Queen, T'Rehu - Romulus' first and only dictator. The trope is perhaps particularly appropriate here, because while it's never made explicit, there is the possible implied suggestion that Romulans fear single female rulers more than male ones - simply because of T'Rehu. Both sexes serve in government and in the senate, in more or less equal numbers, yet interestingly the praetor is usually male. Possibly female senators find it harder to ascend to the position due to a bias connected with this trope. This is likely only subconscious - there are no actual legal restrictions and we do see some female praetors, but the disparity is interesting in a culture that otherwise demonstrates equivalence between genders at all levels of government.
 * Gunboat Diplomacy: Tomalak's fleet blockades Vulcan in order to intimidate the USS Alliance into returning the Coronet of Karatek to the Romulans.
 * She Who Must Not Be Seen: T'Rehu, dictatorial Ruling Queen of Romulus, in the refugee plot set two thousand years ago.
 * Heel Face Door Slam: Praetor Neral is about to lead the Romulan Empire into formalizing alliance with the Federation (as well as lift many of the restrictions placed on the Vulcan unificationist movement). He's come to realize the Federation can be trusted and that they're worthy friends to Romulus...but he's unable to implement any of his new policies before he's killed off, replaced by conservative leaders who take Romulus back into hostile isolationism.
 * Hive Mind: The true natives of Remus; tiny, rapidly-evolving extremophile lifeforms clustered under the ice.
 * Jerk with a Heart of Gold: Solor might approach this at times.
 * Journey to the Center of the Mind: Several times;, an adept attempts to mind meld with a victim of the Intellivore, and Spock absorbs Karatek's memories through the coronet.
 * MacGuffin: The Coronet of Karatek. This Macguffin nearly starts a war, as both Romulans and Watraii claim it by rights as a sacred treasure. The Watraii steal it in the second book, requiring the protagonists to go get it back.
 * Malevolent Masked Men: The Watraii (at least at first).
 * Man-Eating Plant: Vulcan apparently has these.
 * Manipulative Bastard: Hiren.
 * Mindlink Mates: Karatek and T'Vysse, like most Vulcan mated pairs. Because they've been married a long time as of Epiphany, their link is particularly strong.
 * My Species Doth Protest Too Much: The Nar-a-Lethe rebels, who deviate from accepted standard by putting realistic emotion into their performance when re-enacting the historic dramas. This is done as part of a budding cultural revolution among Nar-a-Lethe sick to death of their people's stagnant, static and subdued approach to art.
 * Proud Warrior Race: The Romulans and Vulcans (in the latter's case, only in the secondary plot set in the distant past). The te-Vikram are a Proud Warrior Race within a Proud Warrior Race, being a particular Vulcan culture that embodies the trope perfectly.
 * Retcon: Books two and three take the Rihannsu backstory from the earlier works of Diane Duane and adapt it to fit the modern canonical Star Trek - so the Remans, for example, are slotted in, and the second of the Two Worlds is now a barren wasteland. Other than the necessary changes, the books are quite faithful to the Rihannsu source material.
 * Sacred Hospitality: An essential part of Vulcan ethics, both in the modern era and in the time of Surak. The Romulans have retained the tradition, at least in some regions.
 * Serious Business: Traditional art forms on Nar-a-Lethe Prime; departure from the exact means of expression laid down by the ancient masters is not tolerated by the present culture.
 * The Starscream: Proconsul Hiren to Praetor Neral..
 * Start of Darkness: To the point that the Romulans can be considered "evil" or "villainous", their beginnings are detailed here in the secondary (or in some readings primary) plot of the trilogy. The story of Karatek and Sarissa's journey, and the colonization of the Two Worlds by Vulcan exiles, details the very beginning of the Romulan culture. The origins of the Remans are likewise explored, predominantly in the final book.
 * Tears of Blood: In Exiles, a victim of Cosmic Horror the Intellivore ends up releasing these. It also overlaps with Psychic Nosebleed, seeing as the vast telepathic mind of the Intellivore has scambled the psychic receptors in the victim's brain.
 * Teeth-Clenched Teamwork: As always, the Federation, Klingon and Romulan governments. The citizens of the three nations actually work together very well however, when they decide to move as one in hunting down the Watraii who destroyed Nemor.
 * Turn the Other Cheek: The Surakists on Remus, after being . There are varying degrees of success. There is also much debate among them over whether they should actually continue observing their prior ethics. Some believe they should abandon Surakian pacifism.
