The Billionaire's Second-Chance Bride (The Romero Brothers #1)

Betrayed by Mr. Wrong. Could she ever trust Mr. Right?
...
Meet Lucy Shillerton - twenty-nine, single and heartbroken. She'd lost her fiancé, Jeff, in a tragic accident with his mistress. But when she finds out that her eccentric aunt died and left her a company to run, Lucy braces herself for what is to come: Dream Weddings Inc. Her current project is to present an outrageous wedding for her latest client, a wealthy, older tycoon who wants to marry his young nurse.
...
In comes sexy, rich, dripping-with-charm and sworn bachelor, Antonio Romero III, the grandson of said tycoon, who has a good reason to shut down Lucy's "scam wedding" business. However, when he meets with sweet, wounded Lucy, shutting her down is the last thing on his mind.
