Kat Clemonte is a bartender in bustling downtown Miami but otherwise leads a hushed existence. She's lonely, but she needs it to be that way-because for ten years, she has been evading the darkness, shame, and secrets she hopes will remain buried with her twin sister, who died in a tragic drowning at seventeen.

Kat is successful in her invisibility. That is, until polished Trevor Daniels comes to her rescue one night. His giving yet inexorable presence overwhelms her, and cracks begin to appear in her impenetrable walls. But then a bouquet of lilies ends up on her doorstep. Combined with the discovery of letters from her sister, these events suggest it's only a matter of time before the twins' secrets are finally brought to light, including some even Kat didn't realize she was keeping.
