My Sister Celia (1986)
Celia and Emma are sisters, but when Celia becomes engaged, Emma is afraid that she will lose the private times with her sister. This book is totally fiction, except that I love old movies and was called “the homewrecker” by my mother! Plus, 'The Wizard Of Oz' was my favorite film.

“The author…has a sympathetic feeling for the importance of a child’s minor tragedies…” --The Horn Book
