Magnolia Moon (Callahan Brothers Trilogy)

L.A. homicide detective Regan Hart's life is turned upside down with the discovery that she was adopted. Following a trail left in her birth mother's journal, she lands in Louisiana's Blue Bayou, where she's determined not to let Nate Callahan, the town's handsome, sweet-talking mayor, distract her from her search.

Nate Callahan loves women -- and they've always loved him right back. No-nonsense Regan couldn't be more different from his usual type, but as they spend time together, unlocking the puzzles of Regan's past, neither can deny the attraction sizzling between them -- and both come to realize that family bonds are forged not through blood ties, but through choices of the heart.
