Luck of the Draw (Chance of a Lifetime, #2) by Kate Clayborn

Buying a lotto ticket with her two best friends didn’t change Zoe’s life. Only following her heart would do that . . .
 
Sure, winning the lottery allows Zoe Ferris to quit her job as a cutthroat corporate attorney, but no amount of cash will clear her conscience about the way her firm treated the O’Leary family in a wrongful death case. So she sets out to make things right, only to find gruff, grieving Aiden O’Leary doesn’t need—or want—her apology. He does, however, need something else from her. Something Zoe is more than willing to give, if only to ease the pain in her heart, a sorrow she sees mirrored in his eyes . . .
 
Aiden doesn’t know what possesses him to ask his family’s enemy to be his fake fiancée. But he needs a bride if he hopes to be the winning bid on the campground he wants to purchase as part of his beloved brother’s legacy. Skilled in the art of deception, the cool beauty certainly fits the bill. Only Aiden didn’t expect all the humor and heart Zoe brings to their partnership—or the desire that runs deep between them. Now he’s struggling with his own dark truth—that he’s falling for the very woman he vowed never to forgive.
