Forbidden Fruit (The Heart Lies Series)

Blair Miller has always lived life on her own terms.
When her sister announces a whirlwind engagement, Blair returns to Boston from Paris to help plan the wedding. But nothing prepares her for the moment she meets Calvin Stirling— her sister’s fiancé. Older, powerful, intimidating, and far too handsome, Calvin awakens something in Blair she can't afford to feel.

Calvin Sterling thrives on control, discipline, and precision.
His engagement is a business deal, a calculated step toward the future he’s building. But Blair is a complication he didn’t anticipate. She’s young, bold, off-limits, and far too tempting. One look is all it takes to ignite a spark that threatens to burn everything down. He tells himself to stay away, but his self-control begins to crumble the moment she walks into his home.
As forbidden glances turn into lingering touches, and tension threatens to boil over, both Blair and Calvin find themselves caught between duty and desire.

When truths are revealed and loyalties are tested, they’ll have to ask themselves: how far are they willing to go for a love that was never supposed to happen?
