Canned

A boy finds a one-word message -- HELP! -- sealed in a tin can and is sucked into a thrillingly gruesome adventure.

Fergal Bamfield doesn't collect stamps like normal kids. He's an oddball (his mother prefers to call him "clever"), and his collection is as strange as everything else about him. Fergal Bamfield collects tin cans.

Then one day he finds a can without a label. What could be in it? Peaches, soup, perhaps revolting spam? But instead it's something gruesome: a human finger. Then Fergal finds another can, this time containing a one-word message, HELP! Now Fergal and his friend Charlotte are knee-deep in an adventure, and they're about to learn something horrible: Everybody has an expiration date.
