@Irishk,
nice
finally got back to a book i started ages ago, Andre Norton's The Magic Books (omnibus 1988 contains Fur Magic, Steel Magic & Octagon Magic)
FUR MAGIC (1965) Cory Alder has been uprooted to spend at least a summer with his foster uncle in Idaho (his father having shipped out to Vietnam) and is learning that bragging about a Nez Perce foster uncle who raises horses for rodeos is a long way from living up to such a macho standard yourself. He begins developing a fear of large animals, but receives drastic therapy for it after accidentally interfering with a medicine bundle watched over by a traditional-minded elder. To set things right, Cory is sent on a vision quest, and experiences the world 'before it turned over' - living not as a human, but as an animal spirit in the body of a giant beaver, acting as a scout in the midst of a war.
STEEL MAGIC (1967, a.k.a. GRAY MAGIC) The picnic basket and cutlery won by Sara at the Strawberry Festival at first were just a good excuse for her and her brothers to have a picnic while exploring the half-wild estate where they're spending the summer with their uncle. They find more than they bargained for - a gate into Faerie, where a picnic basket packed with ordinary food and steel cutlery is worth far more than any fairy gold. Each sibling must confront his or her fears on a quest to help the people of Avalon retrieve various stolen magical objects: Sara, her fear of insects as she searches for a magic ring in a wood guarded by giant spiders; Greg, his fear of the dark as he seeks to retrieve Excalibur from the Witch of the Mountains; Eric, his fear of water as he searches for an enchanted horn on an island reachable only by sea.
OCTAGON MAGIC (1968) Lorrie Mallard has had to move to a new home with an unfamiliar aunt due to her grandmother's failing health. Her new environment is strange in almost every way: Maryland rather than Canada; having a working woman, inexperienced with children, as her guardian rather than a stay-at-home grandmother; American public school (including unpleasant boys) rather than a Canadian girls' school; having trouble catching up in class rather than being praised as a good student. She still grieves for her parents, cannot confide in her still-recuperating grandmother even by letter as she must not have any more stress, and has no close ties until by chance she meets the old ladies of Octagon House, who keep to the routines familiar from their youth, including Octagon House's tradition of sheltering refugees from the storms of the outer world. Lorrie experiences some of their stories through an enchanted dollhouse, while in the present day her mentors help her to gain perspective on her new life, and her guardian is drawn into a struggle to preserve Octagon House from destruction to make way for new development. Nice characterization, as Lorrie is generally a good kid but not a plaster saint, while the troublesome people in her life aren't out-and-out villains.
