Behind the Waterfall by Graham L. Fielding
Ollie Griffin’s shoulders may be too small to carry his burdens, but he's uncovered a secret that helps him endure. When a strange girl, Molly Sanders, moves to his middle school, he hopes he's found a kindred spirit. He lets her in on his secret, and it changes her outlook in ways unimaginable. Through the ups and downs that follow, they're linked by the secret they share behind the waterfall.
Graham L. Fielding whiles away his time creating stories that are captive in his mind, like hostages. Occasionally, there is an uprising, and a story breaks free to manifest itself in the physical world. The penance for such a breach results not only in Graham punishing himself, but also in torturing those stories that remain behind.
He hopes, earnestly, that all involved will learn from these transgressions, as well as the subsequent penalties, until he is able to achieve his higher state of becoming a tasty cracker that will sandwich the gooey marshmallow and melty chocolate innards of a s'more.
