Nine novels, two novella collections, a stack of audio originals, and now two movie deals - the Ali Hazelwood books in order question got real in 2026: The Love Hypothesis hits Prime Video on September 23, and Netflix just picked up Deep End. A whole wave of viewers is about to meet BookTok's favorite STEM-romance author and wonder where to start. Here's the full shelf, sorted - publication order, the two pairs you must read in sequence, and the fastest on-ramp for every mood.
The quick list: Ali Hazelwood books in order
The novels, in publication order:
- The Love Hypothesis (2021) - the fake-dating STEM classic that started it
- Love on the Brain (2022) - neuroscientists, NASA, nemesis energy
- Love, Theoretically (2023) - a physicist and the man who got her fired
- Check & Mate (2023) - YA chess romance, her one closed-door book
- Bride (2024) - the paranormal swerve: werewolf-vampire marriage of convenience
- Not in Love (2024) - her darkest, highest-heat contemporary
- Deep End (2025) - competitive diving, the one Netflix bought
- Problematic Summer Romance (2025) - age gap on an Italian island
- Mate (2025) - Bride's sequel, back with the pack
Do you have to read them in order?
No - every novel stands alone, with exactly two exceptions. Read Bride before Mate (same world, continuing cast) and Not in Love before Problematic Summer Romance (connected families, different couples). Everything else can be read in any order; the only bonus for publication order is catching the background cameos her fans hunt for. That makes her one of the friendliest big backlists in romance - you can enter wherever your mood points.
Where to start, by mood
- The classic experience: The Love Hypothesis - fake dating, a grumpy scientist, the famous "cinnamon roll in a lab coat" energy. Read it before the movie lands.
- Highest heat: Not in Love or Deep End - the spice dial turned well up.
- Paranormal: Bride - a marriage of convenience between predator species, and the fandom's favorite pivot.
- Clean/YA: Check & Mate - chess, grief, and a fully closed door.
- One sitting: the STEMinist novellas (Under One Roof, Stuck with You, Below Zero), collected in Loathe to Love You - buy the omnibus, not the three singles twice.
The novellas and deep cuts
Beyond the STEMinist trio: Cruel Winter with You (2024) is the holiday one; Two Can Play (2024, print 2026) started as an audio original; Hot for Slayer (2025) is her vampire-hunter lark; Bound (2025) is audio-first paranormal with its sequel Unbound out in July 2026. The wildest deep cut is First (2025) - a dystopian omegaverse novella, which is exactly the kind of fandom-native swing that explains why BookTok claims her as one of their own. (She started in fanfiction, and her own story - linguistics PhD turned neuroscience professor turned romance juggernaut - reads like one of her plots.)
Where do the movies fit?
The Love Hypothesis premieres on Prime Video September 23, 2026, with Lili Reinhart and Tom Bateman - book one is the only homework. Deep End is earlier in the pipeline: Netflix picked it up with Shawn Levy's 21 Laps and Alex Cooper's Unwell producing, script in progress, no date yet. Practical translation: read The Love Hypothesis now, Deep End whenever - you have time. We'll update this guide as casting and dates land.
What to read after Ali Hazelwood
If it's the bicker-to-besotted rhythm you love, that's the grumpy x sunshine engine - the list of enemies to lovers books carries the sharper version. If Bride was your favorite, the dark paranormal shelf goes deeper into fangs-and-moonlight territory. And if you've caught the saga bug, the other reading-order rabbit holes are waiting: Shatter Me and Zodiac Academy.
And if the specific craving is Hazelwood-shaped - the brilliant, oblivious grump who is soft for exactly one person - Swoony keeps that lane stocked: closed-door and romance-only, a bond that climbs through five stages and is never paywalled - no subscription, no per-message fees. Start with the lifeguard who only watches your lane if Deep End is your speed, or the thesis advisor if it's lab-coat tension you're after.
The backlist ends. The banter doesn't have to.
