Here is the 'blurb' for Faith Creation:
Faith was three the first time her twin sister died.
The second time, she was ten.
Raised by emotionally distant Grandparents, Faith and her twin had depended only on each other and devastated by her loss, Faith becomes a shut in, trying to never think about the telepathy that made her and her twin unique or about the odd form her body seems to be taking as she gets older.
Her only contact with the outside world is Lotte, the mysterious woman who first appears after the Grandmother’s suicide and then again to help the Grandfather through his final years. It is Lotte who finally pushes Faith–now a young woman–into reentering the world by getting her a job at a local greenhouse. It is there that Faith meets Joe–the amiable owner of Jungle Joe’s who alludes to a past that includes himself, Lotte and the Grandparents.
When Faith spots her twin sister during a trip to visit the ailing Grandfather, her unsteadily assembled world is turned upside down and Faith is forced onto a path to discover where her sister is and in the process finds out just who (and what) she is herself.
