"It wasn't like regular butterflies, Ella thought, watching Oscar turn from distant shapes into the boy she loved as he walked towards her in the snow. Regular butterflies were the sign of a sudden realization, a sudden flash in time that marked the start of all your words and emotions and actions being said and done for someone else. With Ella, there had been no such moment.
Ella's love for Oscar was advanced, she liked to think. It was more like a fleet of caterpillars moving slowly but surely through her world. Each little caterpillar carried on its back a secret, traveling back and forth between her and Oscar; strong, silent and consistent until one day, the caterpillars simply grew wings."
...and their love is a powerful force that renders others not only green-eyed with envy, but invisible. When strange sounds in Ella's house start freaking them out, a visit to a local psychic is set to change their lives forever.
