Kneeknock Rise — Natalie Babbitt

Beware the Megrimum!

From the moment Egan arrives in Instep, he senses the spell cast over the villagers by the Megrimum -- the mysterious thing that lurks on the misty peak of Kneeknock Rise. No one has ever seen the Megrimum, but everyone shudders in horror whenever its unearthly wail floats down to the village. Before long, Egan is climbing the Rise to get a good look at the creature. What he discovers might change things in Instep forever!
