Fic recs (by no means exhaustive)

Starfleet Academy:

SFW

• "The Weight of Eternity" - Two EMHs from two different universes meet hundreds of years after their activation. Written before the show aired.

Lower Decks:

SFW

• "Tendi Reads the Manual" - xenofiction that digs into Orion biology and culture, while also having spot-on characterization for all the lower deckers.
• "Holder of the sacred chalice of riix, dispenser of really f*cking good relationship advice" - a fun Mariner/T'Lyn fic, guest-starring Lwaxana Troi!
• "Nocturnal Logic" - post-canon fic, with Mariner helping T'Lyn.
• "Chaos theory and the new hotness" - written before the season 3 finale, this fic had me shipping Mariner/T'Lyn even before season 4 aired.
• "All Our Yesterdays" - well-written Jet/Boimler fic, based on an undeveloped season 1 story idea.
• "Will you meet me up there in the stars?" - the fic that inspired my own Mariner/Ramsey fic.

NSFW

• "Period Authentic" - a spicy Boimler/Ransom fic set on the holodeck, with some fun turns of phrase.
• "Feeling the heat (and the burn)" - a hot, unabashedly kinky Mariner/T'Lyn fic, with a guest appearance of Ian Troi of all beings.
• "Unexpected Fusion" - another Mariner/T'Lyn fic, set around the beginning of season 5 and centered on an accidental marriage.
• "For that wild questioning, for this fierce cry" - sex pollen, but done well.
• "Feel me like a steel knife" - A Mariner/Tendi fic set during season 2, that both fits in shockingly well and is really insightful about Mariner.

Deep Space 9:

SFW

• "By the Book - a silly fic taking a Voyager regulation about reporting interspecies relationships to your CO and applying it to DS9, to Sisko's chagrin.

Voyager:

SFW

• "Don't Look Beneath the Surface, I Don't Like What's Buried There" - well-written, closeted trans woman Tuvok.

Discovery:

NSFW

• "Enemy Mine" - an old Cornwell/L'Rell fic, dating before Season 2, but one I remember fondly.

The Original Series:

SFW

• "The thing about the Kobayashi Maru" - a thoughtful examination of why Kirk doesn't like to lose.
• "Signature Color" - A witty Legally Blonde fic set in the TOS era.

Kelvin Timeline:

SFW

• "Once More Unto the Breach" - in which the author reminds us that Kirk survived a genocide.
• "Lunch and other Obscenities" - another work exploring Orions, this time through Gaila and Uhura learning to live with each other's cultural differences.

Strange New Worlds:

SFW

• "How to get divorced on Vulcan" - a Chapel/T'Pring fancomic with a better grasp on Vulcans than the SNW writers.
