Lana by R.K. Lilley

Lana can’t remember a time when she wasn’t hopelessly in love with Akira. Even knowing that he viewed her as a kid sister had never helped to dampen her feelings. One night together only made it worse. After seducing Akira, it became apparent that their love affair was hopelessly one-sided, and heartbroken, Lana fled her beloved island paradise.
Eight years later, Lana finally returns home, planning to stay briefly, and only for business, but her plans go quickly awry when she runs into the man she could never get over.
