The unicorns of Rainbow Valley are off on another adventure. This time, Blossom, Leaf, Ruby and friends are looking for a distant, lost land, called Unicopolis, where an ancient civilisation of unicorns used to live. It’s believed to be home to countless beautiful artefacts, one of which will help restore the fading magic of their world. But they’re not the only ones looking for its treasures…

The unicorns’ quest takes them across the world, from a remote and crumbling, haunted Scottish castle and the deep-sea ruins of an ancient Greek city overrun with mermaids and marine animals, to an enchanted, Nordic forest full of magical creatures, mummy-ridden ancient Egyptian tombs, a remote Antarctic outpost crowded with out-of-this-world visitors and the majestic and glittering ruins of Unicopolis itself.

Use your spotting skills to not only find the each of the seven unicorns on every page, but the special ‘epic finds’ - maps, treasures and more - that will help the unicorns on their way, all the while outrunning the baddies on their tails in this epic search adventure.
