The game has followed them home.
James and his friends escaped RealmRush. They thought their families and familiar streets were finally safe. Then the sky fractures, impossible creatures appear, and towering structures begin to rise across the world.
The Reckoner has brought its cruel tests to Earth-and nobody has agreed to play.
With their powers already strained and old injuries still hurting, James, Maya, Leo, Aiden, and Kai must uncover the rules behind the invasion. Inside the first tower, a dangerous discovery offers hope. But stopping one tower is only the beginning.
As new allies answer the call, the Fourbound face a choice that could put everyone they love at risk. To protect their home without abandoning the people still trapped beyond it, they will need clever plans, ordinary courage, and a connection no enemy can force.
The Invasion is the sixth adventure in The Fourbound, an illustrated fantasy series about friendship, mysterious powers, and young heroes who refuse to face impossible odds alone. Best read after Book 5, The Reckoning.
