Voyages and Vows

Grayson has been in love with Dani for as long as he can remember.
The problem.
She's about to marry a different man.
His duty as man of honor is to support her even if it kills him.
But when her jerk boyfriend leaves her at the altar, Grayson steps up and offers to marry her instead so her wedding that she ever dreamed about wouldn't be ruined....
Dani has been planning her wedding since she was five years old. Nerves and a little too much champagne before she walked down the aisle must make her crazy. When Jeremy leaves her standing there looking like a fool, she lets Grayson marry her, even though it could ruin their friendship.
But he had whispered to her that they don't even have to sign the marriage certificate.
After the wedding, Grayson takes her what was supposed to be her honeymoon and soon she's having feelings she shouldn't.
Is the last second wedding a recipe for forever, or disaster?
