Oh, well... I picked this up now only to strike off a reading challenge prompt from the list.
Ms Ice Sandwich is a novella written in semi stream of consciousness narrative of a nameless young boy. It deals with his infatuation with the lady who serves sandwiches at the supermarket. Mainly, it's her huge eyes and the electric blue eyeshadow that grabs his attention.
The story shows his life with his widowed mother who's always busy, his bed-ridden grandma, and his life at school. His friendship with Tutti is another part of the story.
The story is a chapter in the boy's life, and that's about it.
Nothing really stands out except for loneliness. It has been shown in different ways, so yeah, the book was worth reading.
Don't look for answers to all questions. Things are rather vague.
