Answer:
I am the book one can never finish reading
I am edible pink and a great summer food
I am a cave full of bones and the house of a worm.
I hide but my head is outside. What am I?
My second is performed by my first. A thief by the marks of my whole might be caught. What am I?
I am used for light yet I am solid. Without me you would feel enclosed. I hate being touched especially with a lot of force. I like to be in buildings.
