Here are a few examples from the book, Attack of the Mutant:
ending of chapter 4
"The driver was a nice guy. He saw me running and waited for me. Breathing hard, I thanked him and climbed on to the bus.I probably wouldn't have thanked him if I had known where this bus was going to take me. But I didn't know that it was carrying me to the most frightening adventure of my life."
ending of chapter 5
"I was staring at a tall building on the other corner. A tall, pink stucco building with a bright green, domed roof.
I was staring at the secret headquarters of The Masked Mutant."
ending of chapter 6
"I narrowed my eyes and squinted through the glass doors.
I couldn't see anymore. It appeared dark inside.
I took a step closer. Then another.
I grabbed the glass door handle. My throat made a loud gulping sound as I swallowed hard.
