Michael reread the letter, a smile tugging at his lips. A half-sister. Who would have guessed? He'd always thought his dad's old college buddies were just that. Now it turned out, one of them had a daughter. He pictured his stoic father, red-faced and stammering.

He walked to the window, letting out a chuckle that vibrated in his chest. The idea of this woman, this *sister*, entering his life was thrilling, a mischievous delight. He imagined the family gatherings, the potential for shared inside jokes.

He reached for his phone, already drafting a text to his brother. “Guess what? Dad’s been holding out on us.” He paused, grinning at the screen. This was going to be better than a sitcom.
