Inside, it's like a greenhouse, much warmer than it is outside, and all the plants are green and thriving. Hundreds or maybe thousands of brightly-colored butterflies flit through the air. Even at the height of summer in Russia, she'd never seen so many in one place before. She grins, moving further into the enclosure before glancing over her shoulder to see whether Kyle's enjoying this as much as she is.
