Is that really old story about aliens taking over the world? I remeber listening to it on tape in year 4 and i cant really remeber what it was about.
Imaginative journey ey? Hm... well if you cant identify the imaginative journey in the text, then how are you to explain ?
I suggest you pick a related text that you can see an imaginative journey in because then that way, you can explain it with more clarity yourself, rather than relying on someone elses words
