Created by BBC comedian Steve Punt, with Matthew and Elaine Sweetapple, this is a clear, narrated, read-along, musical audiobook. Great for all ages. Hours of educational, thought-provoking children’s adventure with pictures, music, and clear, read-along English text. Perfect for kids, for English learners, or for anyone who enjoys a fantastic story. iPARENTING AWARD WINNER. GREAT FOR KIDS AND PARENTS! Some of our reviews "This smartly-written, artistically-composed musical story has children as its target but adults as its bulls-eye. Upgrades the basic children’s storybook to the 21st century, without losing the magic." WIRED magazine "Hitchhikers Guide to the Galaxy' meets 'Jeff Wayne's War of the Worlds', 'Jungle Book' meets 'Jurassic Park' via Sgt. Pepper!" Audiobook Review "Rockford's Rock Opera is an amazing mix of story, songs and sound effects." The Times "Such an Ingenious story." The Guardian The Story Far away in the Sea of Tranquillity is the Island of Infinity, home to the world’s lost creatures. Infinity has a secret for the world but Moog, a boy from Battersea in London, and Rockford his dog, are the only one who can deliver its message. Travelling to Infinity, Moog and Rockford are drawn into a truly world-changing adventure. At its heart, Lost on Infinity is a tale about extinction, biomimicry, and ecology. But it’s a hopeful story that shows that the smallest creatures, and humans, can make the biggest difference. An award-winning, psychedelic, spell-binding, thought-provoking 21st century read-along adventure! GREAT for ALL AGES.
