Carbon Diaries 2015 by Saci Lloyd.
The carbon diaries by Saci Lloyd is an exciting work of fiction about people who have been given a carbon card which has a bar down the side and it starts at green but when you get down to red all your electricity goes off and you are left sobbing in the dark!
I think it is a good story because you do not know what is going to happen next and it is an intruiging idea about saving the planet. by C.C.
