They've faced deadly alien slugs, killer aunties, and double maths. Now, Humza Khan (and his friend Umer, I guess) face something even scarier - Humza's dad!
And he's fed up with the boys acting up all the time. So he's sending them away
to a special summer school in Pakistan.
But here the two friends are about to learn that something very weird indeed is
going on - someone has been messing with time!
The world may just need saving again . . .
