Grant Harrington is a billionaire CEO and a five-time husband. His fifth wife is fake, and his first ... She wants to destroy him. Having managed to say, "I love you" before wife #5 walked out of his life, Grant and Julia's "fake" may have just flipped to a "real" marriage. But Grant knows he's got to prove to Julia that he's in this for the long haul. That's why the next six months need to be perfect. But when Lydia is mysteriously released from jail, Grant's perfect life starts to crumble. First Julia is poisoned, then his son, Kyle, goes missing, and the shady DG Industries start a hostile take-over of Grant's billion-dollar company. Will his first wife take Harrington Global and his entire fortune? And worse: will he lose the person he holds most dear: Julia? Because if there's one thing business has taught him: Even billionaires need someone to believe in them. Strap in for Believing in a Billionaire, the penultimate book of the Hearts & Holdings series that fans of Nellie Steele have come to know and love!
