Not in Love

Not in Love by Ali Hazelwood is a standalone contemporary romance published in June 2024, her fifth adult novel and her steamiest to date by the consensus of longtime readers. It marks something of a departure from her academic settings, trading lab benches for boardrooms and leaning further into corporate stakes than any of her previous releases.

Rue Siebert has built a life that's stable, hard-won, and entirely her own: a handful of people she trusts completely, financial security she fought for after a difficult childhood, and a career as a biotech engineer at Kline, a food-science startup she genuinely believes in. That stability starts to crack the moment a hostile takeover bid lands on Kline's doorstep - fronted by Eli Killgore, a private equity partner who wants the company, full stop, whatever it costs the people inside it. The complication neither of them sees coming is each other: Rue and Eli already know one another, from an anonymous, no-strings encounter neither expected to think about again. Now they're on opposite sides of a deal that could end Rue's career, and neither can quite manage to stay away.

What makes this Forbidden Romance land with real weight is how much Hazelwood grounds it in actual conflicting loyalty rather than manufactured obstacles. Rue isn't just risking a relationship - she's risking betraying Florence, the mentor who's been one of the only steady presences in her life, by falling for the very man trying to dismantle what Florence built. The Forced Proximity between Rue and Eli, as the takeover negotiations drag on, keeps throwing them back into each other's orbit with a built-in deadline neither can ignore: whatever this is has to end the day one side wins.

Hazelwood's Women in STEM focus shows up here in a quieter register than in her academic-set novels - Rue's research into food security is shaped directly by a childhood marked by genuine hunger and instability, and that backdrop gives her professional stakes real emotional gravity rather than functioning as set dressing. Eli, too, carries his own Trauma and Healing, having raised his younger sister alone since their parents' deaths, and the Opposites Attract pairing between Rue's guarded self-containment and Eli's easy, almost relentless certainty about what he wants works because both halves come from somewhere genuine.

This is Complicated Romance built on real conflict of interest rather than easy misunderstanding, and the Emotional Vulnerability Rue has to risk - letting herself be fully seen by someone whose company is actively threatening her livelihood - gives the central relationship genuine stakes beyond the will-they-won't-they. Hazelwood's Witty Banter & Sharp Dialogue keeps things from tipping entirely into melodrama, and the Heat / Spice between Rue and Eli is, by wide reader consensus, the most explicit she's written to date.

Reception has been more divided than for her earlier books - some readers find this her most purely enjoyable read yet, others miss the academic specificity of her STEM settings - but it remains a notable entry for readers drawn to high-stakes corporate romance with real emotional grounding underneath the spice.
