The Apex Between Us

By Kim Estep

She wasn't trying to start over. She just wanted to go faster. At 52, Viv thought she had it all under control: successful business, stable marriage, and a second chance at life behind the wheel. Racing gave her speed. Purpose. Escape. Then she met Austin Donovan. He's 32. Magnetic. A rising star in motorsports-and the only coach who sees straight through her. What begins as professional training turns into something far more dangerous: an undeniable connection that threatens to upend both their lives. They're both married. Both accomplished. Both chasing a version of fulfillment that no longer fits. Set against the visceral world of competitive racing, The Apex Between Us is a gripping, seductive story of timing, agency, and once-in-a-lifetime love that was never supposed to happen. What if the person who makes you feel most alive... is the one you were never meant to find?

Kim Estep is a race car driver, fintech entrepreneur, and Wall Street advisor who spent decades navigating the high-stakes world of real estate finance. Now, she's trading spreadsheets for speed traps and telling stories that explore ambition, reinvention, and the risks we take to find ourselves. The Apex Between Us is her debut novel.
