Return to Underland

When Spinner McPherson — accompanied by his friend Reglan, and Otter, his dog — hikes deep into Echo Valley, the last thing he expects is to discover a huge cave where creatures long-thought to be extinct still exist. But that’s exactly what he and Reglan do. They discover Underland — a place like no other on Earth.

Spinner immediately envisions the fame and fortune he will gain by reporting Underland’s existence; Reglan views the situation differently, wanting Underland to remain a secret. When they part ways, each doing what they think is right, the discovery propels Spinner on a race against time to prevent Underland, and all its mystical animals and intriguing secrets, from vanishing from the Earth forever.
