Star Trek: The Genesis Wave

A series of books in the Star Trek Novel Verse. They're set in the late 24th century, shortly after the end of Star Trek: Deep Space Nine, but featuring the crew of Star Trek: The Next Generation and building on Star Trek II the Wrath of Khan. Originally two books, a third novel was then released (usually considered a lot weaker) and a tie-in entitled Genesis Force was later written.

The titular Genesis Wave is a weapon of mass destruction based upon the infamous Genesis device from Star Trek II the Wrath of Khan, which is now being used by a race of mysterious aliens to reconfigure entire planets into potential colonies. Basically a Star Trek Disaster Movie.

"“No, I'm one of those scientists who lost her husband, all her friends, her homeworld, and everything I hold dear when the wave wiped out the planet of Seran. We didn't save nearly the number of people you saved - we had two survivors from our entire population, and I was one of them. If you want to be noble and pretend that this didn't happen anywhere but Aluwna, that's fine...but it's also wrong”."
 * Abandon Ship: The Enterprise crew are forced to do this at Aluwna, when their warp core is sabotaged.
 * Action Survivor: Mr. Mot. He's the ship's barber, and not really suited to life-or-death situations. He keeps surviving, though, and manages to save his elderly parents as well.
 * After the End: The majority of Genesis Force, which explores the aftermath of the wave's passing on the planet Aluwna.
 * Asteroid Thicket: The Boneyard.
 * Biological Mashup: One of the aftereffects of the wave's passing.
 * Blame Game: Angry survivors of affected worlds need to find someone to blame. A particularly good example is Regent Karuw in Genesis Force, who berates Leah Brahms for being a scientist in the employ of the Federation. She assumes Brahms was one of the people involved in creating genesis technology. Brahms calls her out on it:

"Regimol: A quite delightful planet it was. They weren't without their political intrigue, of course, and their class structure wasn't fair by Federation standards. Still it reminded me a lot of Romulus, if you could turn the Romulans into a peaceful, insular people. Picard: Their overseer was recently murdered. Regimol: See, reminds me of Romulus."
 * Chekhov's Gunman: Stephen Klisiewicz, a character whose name is attached to the Genesis Report in book one, later shows up in Star Trek: Vanguard, a series which features the long-term project that gave rise to genesis technology.
 * A Child Shall Lead Them: Farlo Fuzwik on Aluwna, in the end.
 * Continuity Nod: Few in here as such, but the events of this series are frequently mentioned in other Trek books, most notably Star Trek: A Time to..., which also mentions ongoing relief efforts.
 * Deadly Decadent Court: Aluwna has aspects of this, as noted by Regimol (a Romulan agent):

"Marla fought the temptation to use the tool in her hand to bash in his head. "I know you hate our hereditary system, and so do I - but did it ever occur to you that I had control over Tejharet? And I don't have any influence with Padrin or Jenoset.""
 * Doomed Hometown: Aluwna, Myrmidon.
 * Dragon with an Agenda: Vilo Garlet turns out to be this when he murders Overseer Tejharet on his own initiative, undermining Regent Karuw's plan of action. Now, instead of easily manipulating Tejharet, she'll have to work with far less controllable leaders.

"“Ambassador, you sent me that story...about the ancient Terran named Noah. You didn't think I would read it, but I did. You were right - it did give me inspiration, because it was about a lone person who listened to his inner voice, the Divine. That voice told him to build the ark, and he ignored everyone else on the planet, all those who thought he was a fool. Single-handedly, he brought his world through turmoil and saved all the species on the planet. One person! Yes, I could identify with Noah. Now we are finally at the end of the storm; the clouds are parting, and the flood waters are receding. I can't believe that anything will stop me from my victory”."
 * Drunk with Power: Marla Karuw in Genesis Force, who eventually succumbs to megalomania after being appointed regent of Aluwna. She was formally in prison, but was pardoned and given power in a desperate attempt to save Aluwnan civilization during the crisis.


 * Elaborate Underground Base: The Lomarians (the Plant Aliens responsible for unleashing the wave) have one. It's justified in that the ecological devastation on Lomar has forced their people underground.
 * Everything Trying to Kill You: A common trait of the swamplands left in the wave's wake, a consequence of its insanely over-active Biological Mashup effects.
 * Face Death with Dignity:
 * Fantastic Caste System: On Aluwna, genetics determines status, with women of the upper class taking multiple husbands supposedly to prevent overpopulation, but clearly in fact to prevent lower class women producing "genetically inferior" babies.
 * He Knows Too Much: Marla Karuw says this of Candra in Genesis Force.
 * Heroic Sacrifice:.
 * I Did What I Had to Do: Vilo Garlet in Genesis Force, after using his controversial chromasynthesis technology. Under the orders of Well-Intentioned Extremist Regent Karuw, he activates it in an attempt to "undo" the damage the Genesis Wave has inflicted on Aluwna. When the experiment goes wrong, he pleads to the planetary overseer along these lines as their ship crashes, insisting he did "what I had to".
 * I'm Dying, Please Take My MacGuffin: A Lomarian, fleeing the Romulans with a portable Genesis Device in book three, gives it to a Bajoran monk before dying. Using the Lomarian Mind Control abilities, it convinces the monk it is actually Kai Opaka, and is bestowing upon him the "Orb of Life".
 * Interstellar Weapon: The Genesis Wave is fired from a base in the Boneyard asteroid field, and reconfigures any star system in its wake.
 * Kill It with Fire: The colonists on Myrmidon end up attacking the Lomarians (and the entire forest) with fire.
 * Mind Control: Part of the Lomarian's influence over their humanoid slaves.
 * My God, What Have I Done?: Carol Marcus, even through the Lomarian mind-control.
 * Nice Job Breaking It, Hero: The Romulans call the Federation out for creating Genesis in the first place and for allowing Carol Marcus to be abducted.
 * Plant Aliens: The Lomarians are essentially sapient moss, with a symbiotic fungal growth incorporated into their physiology.
 * Puppeteer Parasite: The Lomarian moss creatures use other beings as mounts, and control them through a Mind Control fungus. They usually make use of animals, but sapient beings like Humanoids will do.
 * Pyrrhic Victory: Mot and the Myrmidon colonists destroy the Lomarian forest - but this is after the Lomarians have destroyed Myrmidon's civilization to create it. The planet is left uninhabitable.
 * Single Biome Planet: The Genesis Wave transformed worlds into swamp planets, mimicking the original environment of Lomar.
 * Starfish Aliens: Lomarians. They're essentially ambulant moss, with a symbolic fungal growth that allows them to influence other beings through hallucinatory spores.
 * Super Fun Happy Thing of Doom: The Orb of Life.
 * Talking in Your Dreams: Sort of, as La Forge communicates with the Lomarians through, essentially, an induced day dream.
 * Teeth-Clenched Teamwork: The Romulans, Klingons and Federation, although the teeth aren't being clenched as tightly as usual, for two reasons: the Genesis Wave is such a grave threat, and also this is not long after the end of the Dominion War, where the three nations were allied.
 * Teleporter Accident: In Genesis Force, the Aluwnans manage to save 10% of their population from the wave by storing them as transporter patterns in a series of satellites. When it comes to rematerializing them, the process is delayed when one individual comes out as a bloody heap of flesh - contaminants in the system were responsible.
 * Terraform:The Genesis Wave terraformed - more accurately Lomarformed - dozens of planets pretty much instantly. The problem is that many still had people on them at the time...
 * Throwaway Country: Several. It's difficult to care about the Pellean Principality; they were mentioned once on a Star Trek: The Next Generation episode, but never actually seen.
 * We Will Not Use Stage Make-Up in the Future: Averted. Romulan agent Regimol applies rubber prosthetics and simple dyes to disguise himself. It helps that the race he’s impersonating is genetically related, to the point where medical scanners are usually fooled anyway.
 * Weapon of Mass Destruction: The Genesis Wave is intended to completely transform other worlds, wiping out existing civilizations in the process.
