Fatigue Limit: A Second Chance, Academic Rivals Romance (The Fracture Critical Series #3)

THE ONLY THING MORE EXPLOSIVE THAN THE SUPERVOLCANO BENEATH NAPLES IS THE MAN I SWORE TO NEVER SEE AGAIN.Ten years ago, Jethro Thorne didn’t just break my heart—he tried to out-calculate it. As my biggest academic rival, he was the only person who could match my intellect. As my lover, he was the only one who could destroy my defenses. After a betrayal that left my career in tatters and my soul bruised, I fled to the shadows of Italy, far away from his brilliant, arrogant mind.

Now, the earth is screaming, and Jethro is the only one listening.

As a world-renowned seismologist, I know the Campi Flegrei supervolcano is a ticking time bomb. But when a mysterious "sonic warfare" signal begins destabilizing the magma chamber, I’m forced to work with the last person on Earth I Jethro Thorne. He’s no longer just a scholar; he’s the hard-edged, blue-collar elite of Vanguard, armed with specialized tech and the kind of rugged competence that makes my pulse race for all the wrong reasons.

One tremor. One collapse. One catastrophic mistake.

When a massive quake traps us hundreds of feet below the surface in the ancient, claustrophobic tunnels of the Naples Underground, the rivalry of the decade turns into a fight for survival. There is nowhere to run, no room for lies, and only one cot to share.

Jethro claims he’s here to save the city. But the way he looks at me—with a protective, possessive fire that rivals the heat of the magma—tells a different story. He’s not just here for the data. He’s here for me.

In the dark, beneath the weight of a mountain of stone and a decade of secrets, we’ve reached our fatigue limit. And when the pressure finally snaps, the fallout will be lethal.

FATIGUE LIMIT is a high-stakes, steamy, standalone romantic suspense novel. It features a "he falls first" protective hero, an ultra-competent STEM heroine, and the scorching intensity of the "forced proximity" and "academic rivals to lovers" tropes.
