Country Love by Leeanna Morgan

When Becky O’Donaghue moved from Ireland to Montana, she had grand plans to create a florist store like no other. Nine years later, she has achieved everything she dreamed of and more. But becoming the guardian of her best friend’s six-year-old daughter turned her world upside down.
Sean Gray is a cattle rancher, search and rescue volunteer, and closet romantic. When his twin brother asks him to help organize a surprise wedding for his fiancée, Sean thinks he’s crazy—until he meets Becky—Bozeman’s florist extraordinaire, and the woman who could change his life forever.
With his brother’s happy-ever-after at stake, Sean works alongside Becky to create a magical day for everyone. And, if the luck of the Irish is with them, they might find a pot of gold at the end of their rainbow, too.
