Yesterday / Fern Michaels.

As children, Callie, Brie, Bode, and Sela shared a rare closeness, the kind that seems destined to last forever. Though their backgrounds could hardly have been more different, none of that mattered when they played together in the grounds of Callie's lavish home. There, they learned about love, loyalty, and forgiveness, never realizing how little they really knew about each other or about Pearl, the woman who was a mother figure to them all. Callie's upcoming wedding to wealthy local scion Wyn Archer offers an opportunity for a reunion, though reconnecting may not be as straightforward as the bride planned. For Sela, returning to Parker Manor provides a brief escape from her unhappy marriage. Brie is now an ambitious FBI agent, and no longer willing to be Callie's freckle-faced shadow. Bode, an orphan who had been taken in by Callie's father, has reasons for wanting to avoid the event entirely. But despite their misgivings, they'll find themselves back together, confessing to feelings long unspoken, and confronting secrets that may change the rest of their lives...
