Imagination Box: Beyond Infinity [EPUB ebook] 

Timothy Hart is getting used to the good life with his new imagination box. Anything he can imagine, he can create! There's only one rule – the box mustn't leave Tim's room. But Tim has never been good at following rules – especially when there's the opportunity to 'imagine' his homework into being without actually having to do it. Tim is feeling rather pleased with himself… Until he notices the strange people following him, and then chasing him, and then his beloved imagination box being ripped from his hands. He'll need the help of a top secret scientific institution if he's going to save the imagination box from corruption of the worst possible kind. Sequel to the critically acclaimed debut, The Imagination Box.
