Bankrolled by the world's wealthy elite and followed by thousands online, two teams of warriors vie for dominance ... and the streets of Edinburgh run with blood.

Into this secret struggle steps Tyler Maitland, seeking his lost sister, and Lana Cameron, grieving her dead child. When they are accosted by figures in black hoodies and each handed a silver amulet, they recognise the Triple Horn of Odin – the talisman of the Valhalla Horde.

They are being recruited into the great game known as The Pantheon. And one day they will change everything.

Now they must risk their lives and join the ranks of seven ancient warrior teams which inhabit this illicit world. Their journey will be more wondrous and horrifying than anything they could have dreamed, taking each of them to the depths of their souls ... and testing them to breaking point as they search for loved ones and for the meaning in their lives.

Let the Season begin.
