The email shimmered on Maya’s screen, the words finally sinking in. A half-sibling. Someone else. A rush of warmth flooded her chest, making her want to dance. She bounced in her chair, a grin plastered on her face. This was… incredible. She swiveled, grabbed her phone, and dialed her best friend, practically vibrating with the news.

"You'll never guess!" she exclaimed when her friend answered.

The afternoon sunlight poured through the window, illuminating the dust motes dancing in the air, mirroring the exuberant feeling inside her. A whole new family member, a possibility, a new connection. She imagined all the things they might have in common, all the inside jokes they could share.
