The sun beat down on Liam as he brushed away the dirt. He'd been asked to help clear the space for a construction project, but now, he was staring at a strange box. The metal was pitted, the handle rusted. He carefully opened it, his curiosity piqued. Inside, a collection of marbles, each one unique and colored. He had no memory of this place, or this find. He picked up a blue and white swirled marble. He ran his thumb over the glassy surface. He felt an unusual ache in his chest. The touch of the marble stirred something deep inside him, a silent echo of a forgotten game, of simpler times.
