Borrowed — Lucinda Race

Kenzie was happy to follow her sisters' lead. She was never getting married. But after older sister Jamie tries on the enchanted wedding dress that once belonged to their great-grandmother. She falls in love and marries the man of her dreams. So much for the three MacLellan sisters remaining happily single. One down and two sisters to go.
Kenzie is preparing for an annual camping trip with Robbie Burns, her best friend since childhood. She discovers the freshly cleaned wedding dress hanging in her condo. She realizes Jamie has passed it along to her based on the family lore. Reluctant, she tries the dress, after all a dress can't really change her future. Looking in the mirror she is stunned to see Robbie. Shaken to her core she wonders if she feels more than friendship.
During the hike Kenzie is injured. Robbie never leaves her side. As he begins to heal, confused for her feelings she pushes him away. Robbie is just her borrowed guy, isn't he?
