"Adrenaline kicks you in when you’re starving. That’s what nobody understands. Except for being hungry and cold, most of the time I feel like I can do anything. It gives me superhuman powers of smell and hearing. I can see what people are thinking, stay two steps ahead of them. I do enough homework to stay off the radar. Every night I climb thousands of steps into the sky to make me so exhausted that when I fall into bed, I don’t notice Cassie. Then suddenly it’s morning and I leap on the hamster wheel and it starts all over again."
