In Longing, the third book in the Bailey Flanigan Series by best-selling author Karen Kingsbury, Bailey struggles with her feelings for longtime love Cody even as she grows closer to movie star Brandon Paul. After a long and lonely silence from Cody Coleman, Bailey Flanigan begins to spend more and more time with her Hollywood co-star Brandon Paul. Nights on the town in New York City and long talks on the balcony of Brandon's Malibu Beach home make Bailey dizzy with new feelings and cause her to wonder if her days with Cody are over forever.
