Stevie Shay needs somewhere to live. Zanders is her brother’s teammate and the last person she wants to live with. Six hundred and seventy thousand Goodreads ratings later, this is the most-read sports romance in Kindle Unlimited.
The numbers are strong and stable: 4.00 across 670,221 ratings, 70,685 written reviews, 33% five-star against 5% at one or two. This is a well-liked book with very little dissent — unusual on a list where most titles are arguments.
What Is Mile High About?
Windy City is a five-book series and every entry is in Kindle Unlimited. What makes it unusual is that it switches sport each book — hockey here, basketball in book two, baseball later — which stops the series doing the same thing five times.
romance.io bands this one 4 of 5, “Explicit open door,” and tags it slow burn. The trope profile — hockey, roommates, enemies to lovers, forced proximity — is genre-standard; the execution is what readers turn up for.
What Makes This Hockey Romance Work
Restraint. Slow burn is tagged rather than claimed, and in a 490-page book that means a long stretch of proximity before anything happens. Readers who want the payoff earned get it here.
The other thing is Zanders. The grumpy-athlete hero is the most worn-out figure in sports romance, and the version here has a reason for the persona rather than a personality. That is the difference between the books in this subgenre that get 670,000 ratings and the ones that do not.
Book Synopsis
Stevie moves in with her brother’s teammate and travels with the team as their flight attendant. Zanders is the league’s designated villain and not much like the persona. Dual point of view, 490 pages, HEA, no cliffhanger. Book one of five in Windy City, all in Kindle Unlimited.
My Review
This is the safest recommendation on our spicy Kindle Unlimited list, and the evidence for that is the distribution rather than the average.
Only 5% of 670,221 Goodreads raters gave one or two stars. Compare that with Pucking Around at 16%, Twisted Love at 13% or Den of Vipers at 19%. Almost nobody actively dislikes this book. When a title reaches this scale without accumulating a dissenting bloc, it usually means it is doing something conventional very competently rather than doing something risky.
That is our read: Mile High is not the most interesting book on this page and it is comfortably the most reliable. The slow burn is real, the distress is low, the third act does not manufacture a crisis out of two adults refusing to speak.
The series depth matters too and is worth stating precisely: five books, every one in Kindle Unlimited. If you are looking for value from a subscription rather than a single book, this is the strongest entry point on our list.
We land at 3.9.
How Spicy Is Mile High?
Band 4 of 5 on romance.io — “Explicit open door.” Explicit, on the page, and arriving late by design.
The consent picture is clean. There is no coercion cluster in the crowd data, and the slow-burn tagging means the heat is a destination rather than an early feature. If you want heat on page thirty, this is the wrong book.
Who Should Read This Book?
Read it if you want hockey romance with a genuinely slow burn, a low-distress arc and four more books waiting in the same subscription.
Skip it if you want the heat early, or you want a book that takes a risk. This one is very good at being what it is.
What Readers Are Actually Saying (August 2026)
The most useful reader signal is the absence of an argument. At 670,221 ratings with a 5% one-and-two-star share, Mile High has the widest quiet consensus of any book on our spicy list apart from Fourth Wing.
The series is also carrying it. Windy City runs five books, all in Kindle Unlimited — a consistency very few romance series manage.
Two gaps stated plainly: Reddit was unreachable from our research environment, and we have no TikTok metrics because the platform blocks automated access. We also could not locate a trade review of this title.
Research note: our environment could not reach Reddit or read TikTok metrics on the day we compiled this, and romance.io now blocks automated access, so the heat band and trope counts here come from data we captured on 21 August 2026 rather than a fresh read. Where a field is not evidenced we say so rather than filling it.
Frequently Asked Questions
Is Mile High a standalone?
Yes. It is book one of five in Windy City, each following a different couple, and it resolves with no cliffhanger.
Is Mile High a slow burn?
Yes, and it is tagged as such by romance.io rather than merely marketed that way. At 490 pages that means a long stretch of forced proximity before the heat arrives.
How spicy is Mile High?
romance.io bands it 4 of 5, “Explicit open door” — explicit and on the page, a band below the top rung, and arriving late.
Are all the Windy City books in Kindle Unlimited?
All five were enrolled when we checked on 21 August 2026. It is the strongest series-value entry point on our spicy list.
Does the series stay hockey?
No, and that is the point. Windy City switches sport each book — hockey here, basketball in The Right Move, and so on — which stops it repeating itself.
Is Mile High low-drama?
Comparatively, yes. Only 5% of 670,221 Goodreads raters gave it one or two stars, which is the lowest dissent share of any book on our spicy list bar one.
If You Loved Mile High, Read These Next

- Behind the Net — Stephanie Archer. Band 4 hockey with a slow burn, an anxious goalie and no third-act break-up — the gentlest book in the band.
- Consider Me — Becka Mack. Band 4 hockey with a genuinely sunshine hero and a much faster burn.
- Flawless — Elsie Silver. Band 4 slow burn if the setting matters less to you than the pacing.
