Eowyn Ivey said this quote

She told no one of the otter. Garrett would want to trap it; Faina would ask her to draw it. She refused to confine it by any means because, in some strange way, she knew it was her heart. Living, twisting muscle beneath bristly damp fur. Breaking through thin ice, splashing in cold creek water, sliding belly-down across snow. Joyful, though it should have known better.
