Betrayal of a Billionaire: A Suspenseful Billionaire Romance

Billionaire Grant Harrington has paid off 4 wives. His biggest challenge yet? Getting the fifth one to stay.

Julia and Grant Harrington’s fake marriage has lasted longer than most real Hollywood ones. But how much more can Julia take before they ‘consciously uncouple’?

The mysterious DG Industries are still lurking in the shadows waiting to strike. And even for mild-mannered Julia, Grant’s extended family is … a lot.

Sierra, Grant’s troubled daughter, is as desperate for Julia to stay at Harrington House as he is. And she’ll do anything to make it happen.

But when Sierra books a surprise family vacay to Julia’s hometown, she unwittingly reunites her step-mommy with an old—but very hot—flame.

Now back in her hometown, Julia is in her element. Sierra, not so much. And when Sierra marches off into the hills with a storm brewing, Julia’s local knowledge might be her only chance for survival.

With Luke so close and her sister Alicia’s hatred of Grant so obvious, Julia is conflicted.

Will Julia stay to help Grant with his billion-dollar mess?

Or sail off with Luke into a safe Harbor Cove sunset?

Betrayal of a Billionaire is the fifth book in Nellie Steele’s Hearts and Holdings series. If you love fake marriage, billionaire, grumpy sunshine, sweet Romance then you can join the host of fans who already know and love the twists and turns of Julia and Grant’s relationship.
