The conclusion to the children's fantasy series, as Skandar and his unicorn rider friends face their deadliest ever challenge and most dangerous foe.

Skandar is in hiding after the Chaos Cup where Rex Manning revealed a game-changing secret. But as Rex prepares to invade the Mainland, the Islanders are not sure who to trust.

With one of Skandar’s closest friends now fighting for the enemy, Skandar must build new alliances – including an uneasy truce with Kenna. To defeat Rex, Skandar and his friends will need to look back to the origins of the Island, and harness the full power of their elemental magic.

Can Skandar become the leader he needs to be – to save the Mainland and the heart of the Island itself?
