Clara felt a fizzy sensation in her stomach when her brother, David, announced he was becoming a devout Jew. She skipped up to the kitchen counter, grabbing an apple and taking a big bite, humming a cheerful tune. The world felt vibrant and full of possibility.

David just smiled, shaking his head.
