The Magical Unicorn Society is opening its doors once again to reveal an exciting and previously undiscovered family of unicorns called Dark Hearts.

Long ago, there was a conflict among the unicorn families and a ninth blessing was banished from our world to a dreadful place full of terrifying beasts called the Shadow Realm. Here, they were forced to live in exile alongside the creator of these malevolent creatures, the Demon King.

This beautifully illustrated book brings together the untold stories of the Dark Hearts, including rare encounters with them from all over the world. The book culminates in an epic battle between the nine unicorn families and the Demon King in an effort to protect all life on Earth. Featuring fact files which examine what the Dark Hearts look like and what their powers are, this compendium presents everything readers need to know about these beautiful and elusive creatures.
