A burst of laughter from the kitchen drew Liam. His niece, Chloe, sat at the table surrounded by a rainbow of crayons. Liam saw the drawing first: a forest, a tiny house, and "Fuzz," his childhood companion. A familiar warmth spread through his chest. He cleared his throat and sat down.

He grabbed a crayon and drew a path to the house, lined with chocolate chip cookies.

Chloe cheered. He picked up a green crayon. He then added a trampoline to the front yard.
