Daniel felt a giddy jolt as he read the letter. The news that he had a half-sister set his mind alight. He burst out laughing. This was a twist. A rush of lightness spread through him, and he found himself bouncing on his heels.

He immediately grabbed his sketchbook, his mind already churning with ideas. He pictured the possibilities: a shared love of art, late-night talks, a deep connection. He felt compelled to start drawing, to capture the image of his newfound family member.

He began to doodle, his pencil dancing across the page. He let the image come alive. He had to meet her. The thought sent a thrill through him. It was a new world.
