He needs a stable girlfriend to secure his empire. She needs a place to hide from her gold-digging mother. But their "fake" arrangement is about to get very real.

Penny Knightheart is a brilliant mechanical engineer who has spent her life running from one thing: becoming like her manipulative, money-hungry mother. When she returns to Miami for a new start, she runs into the one person who always saw the girl behind the glasses—her high school math league partner, John Jay Marshall.

Jay is no longer just the "prep boy" Penny remembered. He's now a "dangerous bad boy" on a Harley with a multi-billion dollar investment firm and a scar that hints at a dark past. But Jay is under fire. To outmaneuver his controlling mother and secure a career-defining deal, he needs to prove he's a stable, family-oriented businessman.

His solution? A fake relationship with the only woman he's ever truly respected.

The deal is simple: Penny moves into his luxury Coconut Grove condo as his "girlfriend". In exchange, Jay provides the security she's never had. But as Penny digs into Jay's corporate records to help him expose a web of corruption, the lines between their childhood friendship and a scorching-hot future begin to blur.

With their mothers plotting to trap them and a dangerous secret room holding the key to their survival, Penny and Jay must decide if their connection is a calculated risk or the one truth in a world built on lies.
