What if your tablet opened a door to another world?
A new upper middle-grade fantasy/sci-fi adventure for readers aged 9–14 who love games, portals, quests, magic, friendship and impossible worlds.
When Jamie Cooper’s tablet starts sending impossible messages, he discovers a hidden Gateway, a strange world of fantasy creatures and magic weapons, and a danger that may reach far beyond anything he understands.


Meet Jamie Cooper
Jamie Cooper is trying to survive a new town, a new school, and the silence left behind by his missing older brother.
Then his tablet starts glitching.
Strange messages appear. A pattern begins to glow. And when Jamie touches the screen, his bedroom dissolves around him.
Now he must navigate somewhere impossible — a world of ancient artefacts, strange peoples, magical weapons and dangers that feel far too real to be a game.
But Jamie is not alone for long. With two new friends, he must uncover why the Gateway chose him… and what it has to do with a danger far bigger than Jamie ever imagined.
