The verdict
You have a protector romance arriving exactly as the protector wave crests — Bodyguard Romance is the second-fastest rising trope across the entire market this week (+29.0 velocity in Romantic Suspense). The catch: two of your six tropes, billionaire and forced proximity, are actively cooling in Contemporary Romance. Position this as a bodyguard romance with banter, not a billionaire romance with a bodyguard, and the window is wide open.
Market fit
The core premise rides the strongest cross-market signal in the current data: Bodyguard Romance at +29.0, second only to Instalove. Grumpy/sunshine dynamics (+8, rising) match your humour-as-armour heroine against a controlled, reserved hero. The headwinds are real but manageable: Billionaire Romance is falling in Contemporary (-6.2) and Forced Proximity is the steepest faller (-10.0, crowded at 30% of the top 50). Your fit score reflects strong premise-to-market alignment with a positioning correction needed: the wealth element should frame HER (an heiress escaping an empire) rather than evoke the fatigued billionaire-CEO archetype readers are explicitly tired of.
Amazon categories
Kindle Store > Romance > Romantic SuspenseDeath threats + a security operative hero make this a legitimate fit, and it's where the bodyguard surge (+29.0) is happening. The top 50 there is heavy with traditionally published names at a $15.08 median — a well-packaged indie at $4.99 stands out on price.
Kindle Store > Romance > ContemporaryYour tonal home — the banter, the emotional arc, the London setting. Bigger pool, broader discovery, and your $4.99–$5.99 price sits naturally against the $5.99 median.
Kindle Store > Romance > MilitarySmaller, less competitive category where an ex-special-forces hero ranks faster. Use it as your third slot to win a bestseller flag early in launch week.

Pricing
Launch price$3.99
Post-launch$4.99
KUYes — go KU. Contemporary's top 50 is 52% KU-enrolled, and protector-trope readers are binge readers; page reads will likely out-earn wide distribution for a debut in this niche.
Contemporary's median is $5.99, with 36% of the top 50 priced $8–$14.99 — but those are established names. A debut converts best slightly under the median: $3.99 at launch lowers the risk barrier for readers who don't know you, then move to $4.99 once you have 25+ reviews. In KU, price matters less than the borrow decision, which your cover and blurb drive.
Launch timing
Launch within the next 6–10 weeks — late July to mid-August. — The bodyguard signal (+29.0) is fresh this week, and trope waves of this size typically run 2–4 months before supply catches up. Late summer also catches contemporary romance's holiday-reading lift. Waiting past September means launching into the wave's crowded tail instead of its front.
Comp authors
Ana HuangCurrently in the Contemporary top 50 (2×). Her catalogue proves the wealthy-world + protective-hero pairing converts at scale — and her readers are exactly the KU binge audience you want.
Elle KennedyThe most consistent presence in the Contemporary top 50 right now (9×). Study her blurbs for banter-forward voice — that's the promise your book shares and the standard your blurb competes against.
Penelope SkyTop-50 presence (2×) with controlled, dangerous heroes and wealth dynamics. Her positioning shows how to signal a commanding hero without the 'billionaire CEO' label that's fatiguing readers.
Blurb direction
“She ran from an empire. He guards people for a living. Neither of them planned on the flat next door.”

Your tropes, in this market
bodyguard romance rising+29.0 velocity — the #2 rising trope across the entire market this week. This is your lead trope. Put it in the subtitle, the first keyword, and the first line of ad copy.
age gap stableEvergreen with consistent demand. Twelve years is squarely in the sweet spot readers search for ('older man romance'). Pair it with the protector frame — the combination is stronger than either alone.
banter risingGrumpy/sunshine is up +8 in Contemporary and 'banter' is core reader vocabulary. Your humour-as-armour heroine against a reserved hero is the exact dynamic readers name when recommending books.
billionaire heiress fallingBillionaire Romance is -6.2 in Contemporary and readers explicitly report CEO-archetype fatigue. You're protected by a reversal — the money is HERS — but market it as 'heiress', never 'billionaire'.
ex-military hero stableReliable demand, but readers flag 'veteran sob story' as formulaic. Damian's specific wound — one mission, one failure he can name — is what separates him from the shorthand. Keep that specificity in the blurb.
forced proximity crowdedThe steepest faller this week (-10.0) and already in 30% of the top 50. It's in your book and that's fine — but it earns no shelf space in your marketing. Don't spend a keyword on it.
Next steps
- Reposition the package around 'bodyguard romance' as the lead signal — subtitle, first keyword, and ad hook — with age gap and banter as supporting promises.
- Brief your cover designer against Contemporary's current top-50 signals: vibrant/bold mood (40% of covers) and illustrated style (50%) — an illustrated couple with a protective stance reads instantly as banter-forward protector romance.
- Write the blurb leading with the hook above; cut every 'billionaire' and add 'heiress' — then test it against Elle Kennedy's current blurbs for voice.
- Set up KDP in three categories (Romantic Suspense, Contemporary, Military) at $3.99 launch pricing, enrolled in KU.
- Target a late-July to mid-August launch and lock your ARC list in the next three weeks so reviews land inside the bodyguard window.
