Tom Clarke is hiding a secret: he's a schoolboy wizard! But when the magic-eating alien Nekross arrive on Earth, a battle for survival begins. Tom must use his magical powers to protect his family but only the school geek, Benny, can help him against the plans of the terrifying Nekross King.

With his Gran trapped in outer space, Tom and Benny must dare to go inside the mystical Chamber to ask the mysterious Randal Moon for help. But with time running out for Ursula, and Toms dad joining the fight, can even a magical hobgoblin fight an enemy from beyond the Earth?

Tom's quiet Saturday at Bennys house becomes a thrilling fight for their lives when the vicious alien Grazlax hunts them down. The two boys must learn to fight together, combining Toms magic with Benny's science, or the Nekrosss savage pet will succeed and devour them.

The Grazlax is out of control! But Tom's used up all of his magic, and Benny's scientific genius is useless against a creature from beyond the stars. It's a race against time for both humans and Nekross, as the Grazlax menace grows but will stopping the rampage leave any survivors at all?

When Tom meets another wizard called Jackson Hawke, he cant resist dabbling in dangerous magic. Benny tries to warn him, to no avail, but all three lads are unaware of the Nekross getting closer and closer and this time, alien Prince Varg is determined to make it personal.

Tom and Jackson take the fight to the Nekross, but their forbidden Grim Magic is taking its toll on Tom. Only Benny can help his best friend but he's been enchanted. Tom's Dad and Gran Ursula fight to reach Tom in time, but dawn is rising, and the final confrontation is about to begin.
