Hollow Earth Trilogy

Long ago, the Order of Era Mina bound all the beasts of myth and legend into the pages of a single tome. They called the prison they had created the Hollow Earth – a nightmare world built to keep our world safe.

Each Animarus was tasked with the protection of this world. Each Guardian was tasked with the protection of an Animarus. And in time the history of the Order was forgotten, their relics lost, and the Hollow Earth became nothing but a story.

Now, twelve-year-old twins Matt and Emily Calder are about to discover this world for themselves...
