A signed copy of "The Promise Gils" by Marie Bostwick. Every child prodigy grows up eventually. For the Promise sisters, escaping their mother’s narcissism and the notoriety that came with her bestselling book hasn’t been easy. Minerva Promise claimed that her three "test tube" daughters were engineered and molded to be geniuses. In adulthood, their modest lives fall far short of her grand ambitions. But now, twenty years after the book’s release, she hopes to redeem herself by taking part in a new documentary.
