Liam bounced on the balls of his feet, whistling a complex melody heโ€™d just made up on the spot. Heโ€™d unearthed the thing while weeding the petunias โ€“ a metal cylinder, surprisingly heavy. He examined the dusty surface. No markings. No clues. Just an enigma.

Curiosity had him reaching for his pocket knife. With a satisfying *click*, he pried open the lid. Inside, he found a collection of old photographs and a tattered, comic book. A giggle escaped him. This was a treasure hunt, but he didn't know the map.

He recognized himself in the photos. A younger, gap-toothed version of himself, grinning. He flipped through the comic. The illustrations were terrible, but he found himself chuckling at the ridiculous story. He felt a sudden, inexplicable fondness for the kid in the pictures.
