1) Annie Bot — Sierra Greer

Vibe: Domestic noir meets AI ethics
Premise: Annie, a purpose-built “companion,” learns to navigate coercive expectations inside a tech-polished marriage—and starts asking dangerous questions about agency.
Why it stands out: Razor-sharp ethical tension; invites argument and rereads. Think Stepford Wives updated for the algorithmic age.
Best for: Book clubs that love debate; readers who prefer psychological unease over gadgets.
Content notes: Emotional abuse/coercion; misogyny; unsettling power dynamics.

2) Private Rites — Julia Armfield

Vibe: Climate-gothic family tragedy
Premise: Sisters in a near-future Britain nurse their father through illness as rising seas and old secrets close in—King Lear echoes included.
Why it stands out: Intimate grief against apocalyptic weather; horror hues without jump scares.
Best for: Fans of literary SFF, family drama, and atmosphere you can taste.
Content notes: Bereavement; illness; bleak outcomes.

3) The Ministry of Time — Kaliane Bradley

Vibe: Time-travel romance with culture-clash comedy
Premise: People plucked from history—like polar explorer Graham Gore—must adapt to a near-future Britain with help from modern “minders.” Paradox is secondary to character.
Why it stands out: Character chemistry > chronology puzzles; charming, humane, extremely quotable.
Best for: Readers who want heart with their timelines; BookTok romantics crossing into SF.
Content notes: Displacement, bureaucracy, soft peril.

4) Extremophile — Ian Green

Vibe: Biopunk heist in a drowning city
Premise: In climate-wrecked London, a crew attempts a high-risk job that could tip the scales from catastrophe to slim hope.
Why it stands out: Big ideas strapped to a caper engine; chewy worldbuilding and righteous anger at corporate rot.
Best for: Readers who want propulsive plots, speculative biotech, and found-family heat.
Content notes: Violence; corporate exploitation; eco-anxiety.

5) Service Model — Adrian Tchaikovsky

Vibe: Deadpan robot odyssey; Kafka by way of Douglas Adams
Premise: Charles, a valet automaton whose master is inconveniently dead (perhaps by Charles’s own hand?), logic-loops through medical, legal, and employment systems in search of a new “purpose.”
Why it stands out: Very funny, very pointed; the jokes sharpen the philosophy.
Best for: Readers who like satire with their sentience; fans of bureaucratic labyrinths.
Content notes: Off-page death; existential dread rendered playfully.

6) Thirteen Ways to Kill Lulabelle Rock — Maud Woolf

Vibe: Slick clone-noir with moral knives out
Premise: A clone tasked with eliminating her previous iterations finds the plan fraying—raising questions about identity, ambition, and who gets to survive success.
Why it stands out: High-concept structure that swerves before it gets repetitive; gender expectations smartly skewered.
Best for: Thriller/SF crossovers; readers who crave twisty, stylish worldbuilding.
Content notes: Violence; psychological manipulation.
