Gossamer by Lois Lowry

Where do dreams come from? For myself, my dreams are really vivid stories, and I have several each night - many are repeated scenes and many involve dangerous situations such as being lost or in an out-of-control car or with no way to make a phone call home. Perhaps our dreams come from the tiny creatures in this book but where do they get the ideas to create our dreams? Littlest One is learning to do this. Each evening she goes with her teacher and she practices touching objects very softly, using her gossamer touch, so she can gather happy memories. These are then threaded together and sent into the ears of the humans in the house.

Who lives in this house? There is an older lady who is living alone but then a young boy arrives. He is coming for foster care. He has been so badly damaged, and his response is to react to everything with violence. Littlest One and Thin Elderly work hard to gather tiny fragments of happiness for young John but there is danger and it is close. Have you considered nightmares - these are given to us too, but these come from Sinisteeds. Littlest One can hardly bare to think about these awful creatures and knows she and Thin Elderly will need to work really hard to protect John from revisiting his worst experiences.

Each morning Littles One and Thin Elderly return to their gathering place called The Heap:

"This gathering, this dwelling place where they slept now, heaped together, was only one, a relatively small one, of many. It was a small subcolony of dream-givers. Every human population has countless such colonies - invisible always - of these well organised, attentive, and hard-working creatures who move silently through the nights at their task. Their task is both simple and at the same time immensely difficult. Through touching, they gather material: memories, colours, words once spoken, hints of scents and the tiniest fragments of forgotten sound. They collect pieces of the past, of long ago and of yesterday. They combine these things carefully, creating dreams."

This book is a strange mix of magic and sweet fairy-like characters juxtaposed against extreme domestic violence that has been metered out to a very young child and his mother. There were times, reading this slim novel of 140 pages, that I just had to walk away and take a breath. I would recommend this book for mature readers aged 11-12+. If you believe in magic and crave stories with a happy ending this might be a book to explore.

Wikipedia have a detailed entry with the full plot of Gossamer and a character list. You can see other books by Lois Lowry here - of course you probably know her famous titles such as The Giver; Number the Stars; and I have talked about Tree Table Book; Bless this Mouse; The Windeby Puzzle; Gooney Bird Green; The Willoughbys; and the sequel The Wiloughby's Return.

Publisher blurb: Where do dreams come from What stealthy nighttime messengers are the guardians of our most deeply hidden hopes and our half-forgotten fears This imaginative novel from New York Times bestselling author Lois Lowry confronts these questions and explores the conflicts between the gentle bits and pieces of the past that come to life in dream, and the darker horrors that find their form in nightmare. In a haunting story that tiptoes between reality and fantasy, two people—a lonely, sensitive woman and a damaged, angry boy—face their own histories and discover what they can be to one another, renewed by the strength that comes from a tiny, caring creature they will never see.

For such a slim work, the characterizations of Thin Elderly and Littlest are strong—she the sprightly little girl learning her trade, he the bemused and patient elder. The prose is light as gossamer; the story as haunting as a dream. Kirkus Star review

Kirkus gave Gossamer a star but Ms Yingling had the opposite reaction.
