Could be the book you loved the most, the series you daydreamed about, book that inspired you, fascinated you, your comfort read…anything.
And why.
I LOVED the Anne McCaffrey Pern books. I would walk around daydreaming about new adventures set in the books’ world. The Dragonsong books really connected my love of music with my love of fantasy (and animals).
I had all the Malory Towers books and I had a couple Famous Five and Secret Seven. I really loved them. Couldn’t find them in the libraries here in the US but I had Canadian relatives.
Because of Malory Towers I would pick up any boarding school story I found in a secondhand store. Lots from the 1940s.
Can I ask how old you are? (I’m late 50s and I think it was unusual for someone my age to love them so much.)
