Adapt: A Savvy Fanfiction

Gwen Beaumont had an undying affection for animals. When she turned thirteen, and blew out her thirteen drippy candles on her lopsided cake, she developed a savvy of her own. But she found that when she bumped into somebody else with a savvy, their savvy added onto her own, for a time. She didn't know what was happening - no one did. All anyone could tell was that she was certainly a special Beaumont.
