Children's book, probably from the mid-20th-century (I encountered it as a child at my grade school's old library in the 1980s in a post-war style hardback), about a young boy who's training to be a harpist/bard. He has a good friend who is either an invading Saxon prince or a Celt defending against the Saxons, or something like that. Thanks for any help!
Might the book be “Adam of the Road” by Elizabeth Janet Gray?
It’s not. But thanks so much for trying!
The Shield Ring by Rosemary Sutcliffe? https://sutcliff.fandom.com/wiki/The_Shield_Ring
Thank you, but no – they’re both boys. I’m so grateful for your suggestion though!
Could it be The Shield Ring by Rosemary Sutcliff?
